Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122850, here are decompositions:

  • 11 + 122839 = 122850
  • 17 + 122833 = 122850
  • 23 + 122827 = 122850
  • 31 + 122819 = 122850
  • 61 + 122789 = 122850
  • 73 + 122777 = 122850
  • 89 + 122761 = 122850
  • 97 + 122753 = 122850

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 122,850 and was likely granted around 1871.

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

Position in π

The digit sequence 122850 first appears in π at position 7,674 of the decimal expansion (the 7,674ordinal-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.
