Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158418, here are decompositions:

  • 11 + 158407 = 158418
  • 47 + 158371 = 158418
  • 59 + 158359 = 158418
  • 61 + 158357 = 158418
  • 67 + 158351 = 158418
  • 89 + 158329 = 158418
  • 149 + 158269 = 158418
  • 157 + 158261 = 158418

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 158,418 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 158418 first appears in π at position 990,904 of the decimal expansion (the 990,904ordinal-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.
