Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162408, here are decompositions:

  • 17 + 162391 = 162408
  • 19 + 162389 = 162408
  • 131 + 162277 = 162408
  • 139 + 162269 = 162408
  • 151 + 162257 = 162408
  • 157 + 162251 = 162408
  • 179 + 162229 = 162408
  • 199 + 162209 = 162408

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 162,408 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 162408 first appears in π at position 424,192 of the decimal expansion (the 424,192ordinal-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.
