Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178602, here are decompositions:

  • 5 + 178597 = 178602
  • 31 + 178571 = 178602
  • 41 + 178561 = 178602
  • 43 + 178559 = 178602
  • 71 + 178531 = 178602
  • 89 + 178513 = 178602
  • 101 + 178501 = 178602
  • 113 + 178489 = 178602

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 178,602 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 178602 first appears in π at position 708,999 of the decimal expansion (the 708,999ordinal-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.
