Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183900, here are decompositions:

  • 19 + 183881 = 183900
  • 23 + 183877 = 183900
  • 29 + 183871 = 183900
  • 71 + 183829 = 183900
  • 103 + 183797 = 183900
  • 137 + 183763 = 183900
  • 139 + 183761 = 183900
  • 191 + 183709 = 183900

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 183,900 and was likely granted around 1875.

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

Position in π

The digit sequence 183900 first appears in π at position 235,856 of the decimal expansion (the 235,856ordinal-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.
