Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158270, here are decompositions:

  • 37 + 158233 = 158270
  • 43 + 158227 = 158270
  • 61 + 158209 = 158270
  • 109 + 158161 = 158270
  • 127 + 158143 = 158270
  • 157 + 158113 = 158270
  • 193 + 158077 = 158270
  • 199 + 158071 = 158270

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 158,270 and was likely granted around 1873.

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

Position in π

The digit sequence 158270 first appears in π at position 834,942 of the decimal expansion (the 834,942ordinal-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.
