Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490206, here are decompositions:

  • 5 + 490201 = 490206
  • 23 + 490183 = 490206
  • 37 + 490169 = 490206
  • 47 + 490159 = 490206
  • 89 + 490117 = 490206
  • 103 + 490103 = 490206
  • 109 + 490097 = 490206
  • 149 + 490057 = 490206

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 490,206 and was likely granted around 1892.

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

Position in π

The digit sequence 490206 first appears in π at position 15,874 of the decimal expansion (the 15,874ordinal-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.
