Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38240, here are decompositions:

  • 3 + 38237 = 38240
  • 43 + 38197 = 38240
  • 73 + 38167 = 38240
  • 127 + 38113 = 38240
  • 157 + 38083 = 38240
  • 193 + 38047 = 38240
  • 229 + 38011 = 38240
  • 277 + 37963 = 38240

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38240 first appears in π at position 120,859 of the decimal expansion (the 120,859ordinal-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.
