Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158146, here are decompositions:

  • 3 + 158143 = 158146
  • 5 + 158141 = 158146
  • 17 + 158129 = 158146
  • 137 + 158009 = 158146
  • 239 + 157907 = 158146
  • 257 + 157889 = 158146
  • 269 + 157877 = 158146
  • 347 + 157799 = 158146

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 158,146 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 158146 first appears in π at position 160,562 of the decimal expansion (the 160,562ordinal-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.
