Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190408, here are decompositions:

  • 5 + 190403 = 190408
  • 17 + 190391 = 190408
  • 41 + 190367 = 190408
  • 107 + 190301 = 190408
  • 137 + 190271 = 190408
  • 227 + 190181 = 190408
  • 311 + 190097 = 190408
  • 419 + 189989 = 190408

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 190,408 and was likely granted around 1875.

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

Position in π

The digit sequence 190408 first appears in π at position 59,784 of the decimal expansion (the 59,784ordinal-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.
