Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506390, here are decompositions:

  • 43 + 506347 = 506390
  • 61 + 506329 = 506390
  • 109 + 506281 = 506390
  • 127 + 506263 = 506390
  • 139 + 506251 = 506390
  • 271 + 506119 = 506390
  • 277 + 506113 = 506390
  • 307 + 506083 = 506390

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 506,390 and was likely granted around 1893.

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

Position in π

The digit sequence 506390 first appears in π at position 7,358 of the decimal expansion (the 7,358ordinal-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.
