Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40238, here are decompositions:

  • 7 + 40231 = 40238
  • 61 + 40177 = 40238
  • 109 + 40129 = 40238
  • 127 + 40111 = 40238
  • 139 + 40099 = 40238
  • 151 + 40087 = 40238
  • 199 + 40039 = 40238
  • 229 + 40009 = 40238

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40238 first appears in π at position 17,679 of the decimal expansion (the 17,679ordinal-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.
