Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947900, here are decompositions:

  • 7 + 947893 = 947900
  • 43 + 947857 = 947900
  • 67 + 947833 = 947900
  • 97 + 947803 = 947900
  • 127 + 947773 = 947900
  • 157 + 947743 = 947900
  • 181 + 947719 = 947900
  • 193 + 947707 = 947900

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 947,900 and was likely granted around 1909.

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

Position in π

The digit sequence 947900 first appears in π at position 842,769 of the decimal expansion (the 842,769ordinal-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.
