Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182578, here are decompositions:

  • 17 + 182561 = 182578
  • 29 + 182549 = 182578
  • 41 + 182537 = 182578
  • 59 + 182519 = 182578
  • 89 + 182489 = 182578
  • 107 + 182471 = 182578
  • 191 + 182387 = 182578
  • 239 + 182339 = 182578

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 182,578 and was likely granted around 1875.

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

Position in π

The digit sequence 182578 first appears in π at position 33,368 of the decimal expansion (the 33,368ordinal-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.
