Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158570, here are decompositions:

  • 3 + 158567 = 158570
  • 7 + 158563 = 158570
  • 19 + 158551 = 158570
  • 43 + 158527 = 158570
  • 127 + 158443 = 158570
  • 151 + 158419 = 158570
  • 163 + 158407 = 158570
  • 199 + 158371 = 158570

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 158,570 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 158570 first appears in π at position 180,817 of the decimal expansion (the 180,817ordinal-suffix:th 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.
