Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169844, here are decompositions:

  • 7 + 169837 = 169844
  • 13 + 169831 = 169844
  • 61 + 169783 = 169844
  • 67 + 169777 = 169844
  • 151 + 169693 = 169844
  • 163 + 169681 = 169844
  • 211 + 169633 = 169844
  • 277 + 169567 = 169844

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 169,844 and was likely granted around 1874.

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

Position in π

The digit sequence 169844 first appears in π at position 202,892 of the decimal expansion (the 202,892ordinal-suffix:nd 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.
