Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137848, here are decompositions:

  • 17 + 137831 = 137848
  • 71 + 137777 = 137848
  • 149 + 137699 = 137848
  • 251 + 137597 = 137848
  • 281 + 137567 = 137848
  • 311 + 137537 = 137848
  • 401 + 137447 = 137848
  • 449 + 137399 = 137848

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 137,848 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 137848 first appears in π at position 749,963 of the decimal expansion (the 749,963ordinal-suffix:rd 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.
