Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176638, here are decompositions:

  • 29 + 176609 = 176638
  • 41 + 176597 = 176638
  • 47 + 176591 = 176638
  • 89 + 176549 = 176638
  • 101 + 176537 = 176638
  • 107 + 176531 = 176638
  • 131 + 176507 = 176638
  • 149 + 176489 = 176638

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 176,638 and was likely granted around 1874.

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

Position in π

The digit sequence 176638 first appears in π at position 59,345 of the decimal expansion (the 59,345ordinal-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.
