Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40340, here are decompositions:

  • 103 + 40237 = 40340
  • 109 + 40231 = 40340
  • 127 + 40213 = 40340
  • 151 + 40189 = 40340
  • 163 + 40177 = 40340
  • 211 + 40129 = 40340
  • 229 + 40111 = 40340
  • 241 + 40099 = 40340

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40340 first appears in π at position 159,626 of the decimal expansion (the 159,626ordinal-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.
