Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137850, here are decompositions:

  • 19 + 137831 = 137850
  • 23 + 137827 = 137850
  • 47 + 137803 = 137850
  • 59 + 137791 = 137850
  • 73 + 137777 = 137850
  • 79 + 137771 = 137850
  • 107 + 137743 = 137850
  • 113 + 137737 = 137850

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 137,850 and was likely granted around 1872.

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

Position in π

The digit sequence 137850 first appears in π at position 675,821 of the decimal expansion (the 675,821ordinal-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.
