Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51146, here are decompositions:

  • 13 + 51133 = 51146
  • 37 + 51109 = 51146
  • 103 + 51043 = 51146
  • 157 + 50989 = 51146
  • 223 + 50923 = 51146
  • 307 + 50839 = 51146
  • 313 + 50833 = 51146
  • 373 + 50773 = 51146

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51146 first appears in π at position 103,646 of the decimal expansion (the 103,646ordinal-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.
