Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151458, here are decompositions:

  • 7 + 151451 = 151458
  • 29 + 151429 = 151458
  • 61 + 151397 = 151458
  • 67 + 151391 = 151458
  • 79 + 151379 = 151458
  • 101 + 151357 = 151458
  • 179 + 151279 = 151458
  • 211 + 151247 = 151458

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 151,458 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 151458 first appears in π at position 686,881 of the decimal expansion (the 686,881ordinal-suffix:st 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.
