Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101790, here are decompositions:

  • 19 + 101771 = 101790
  • 41 + 101749 = 101790
  • 43 + 101747 = 101790
  • 53 + 101737 = 101790
  • 67 + 101723 = 101790
  • 71 + 101719 = 101790
  • 89 + 101701 = 101790
  • 97 + 101693 = 101790

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 101,790 and was likely granted around 1870.

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

Position in π

The digit sequence 101790 first appears in π at position 554,868 of the decimal expansion (the 554,868ordinal-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.
