Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40258, here are decompositions:

  • 5 + 40253 = 40258
  • 17 + 40241 = 40258
  • 89 + 40169 = 40258
  • 107 + 40151 = 40258
  • 131 + 40127 = 40258
  • 227 + 40031 = 40258
  • 269 + 39989 = 40258
  • 389 + 39869 = 40258

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40258 first appears in π at position 396,326 of the decimal expansion (the 396,326ordinal-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.
