Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708578, here are decompositions:

  • 41 + 8708537 = 8708578
  • 59 + 8708519 = 8708578
  • 71 + 8708507 = 8708578
  • 149 + 8708429 = 8708578
  • 167 + 8708411 = 8708578
  • 191 + 8708387 = 8708578
  • 239 + 8708339 = 8708578
  • 317 + 8708261 = 8708578

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,708,578 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8708578 first appears in π at position 231,150 of the decimal expansion (the 231,150ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
