Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11290, here are decompositions:

  • 3 + 11287 = 11290
  • 11 + 11279 = 11290
  • 17 + 11273 = 11290
  • 29 + 11261 = 11290
  • 47 + 11243 = 11290
  • 113 + 11177 = 11290
  • 131 + 11159 = 11290
  • 173 + 11117 = 11290

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11290 first appears in π at position 11,190 of the decimal expansion (the 11,190ordinal-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.
