Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190406, here are decompositions:

  • 3 + 190403 = 190406
  • 19 + 190387 = 190406
  • 37 + 190369 = 190406
  • 67 + 190339 = 190406
  • 109 + 190297 = 190406
  • 157 + 190249 = 190406
  • 163 + 190243 = 190406
  • 199 + 190207 = 190406

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 190,406 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 190406 first appears in π at position 405,911 of the decimal expansion (the 405,911ordinal-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.
