Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158906, here are decompositions:

  • 43 + 158863 = 158906
  • 103 + 158803 = 158906
  • 157 + 158749 = 158906
  • 379 + 158527 = 158906
  • 457 + 158449 = 158906
  • 463 + 158443 = 158906
  • 487 + 158419 = 158906
  • 499 + 158407 = 158906

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 158,906 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 158906 first appears in π at position 782,762 of the decimal expansion (the 782,762ordinal-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.
