Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578656, here are decompositions:

  • 47 + 578609 = 578656
  • 53 + 578603 = 578656
  • 59 + 578597 = 578656
  • 83 + 578573 = 578656
  • 167 + 578489 = 578656
  • 173 + 578483 = 578656
  • 179 + 578477 = 578656
  • 257 + 578399 = 578656

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 578,656 and was likely granted around 1896.

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

Position in π

The digit sequence 578656 first appears in π at position 77,149 of the decimal expansion (the 77,149ordinal-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.
