Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189550, here are decompositions:

  • 3 + 189547 = 189550
  • 41 + 189509 = 189550
  • 59 + 189491 = 189550
  • 71 + 189479 = 189550
  • 83 + 189467 = 189550
  • 113 + 189437 = 189550
  • 149 + 189401 = 189550
  • 173 + 189377 = 189550

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 189,550 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 189550 first appears in π at position 944,231 of the decimal expansion (the 944,231ordinal-suffix:st 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.
