Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40228, here are decompositions:

  • 59 + 40169 = 40228
  • 101 + 40127 = 40228
  • 191 + 40037 = 40228
  • 197 + 40031 = 40228
  • 239 + 39989 = 40228
  • 257 + 39971 = 40228
  • 359 + 39869 = 40228
  • 389 + 39839 = 40228

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40228 first appears in π at position 14,137 of the decimal expansion (the 14,137ordinal-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.
