Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101894, here are decompositions:

  • 3 + 101891 = 101894
  • 31 + 101863 = 101894
  • 61 + 101833 = 101894
  • 97 + 101797 = 101894
  • 157 + 101737 = 101894
  • 193 + 101701 = 101894
  • 241 + 101653 = 101894
  • 283 + 101611 = 101894

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 101,894 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 101894 first appears in π at position 818,805 of the decimal expansion (the 818,805ordinal-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.
