Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40528, here are decompositions:

  • 29 + 40499 = 40528
  • 41 + 40487 = 40528
  • 101 + 40427 = 40528
  • 167 + 40361 = 40528
  • 239 + 40289 = 40528
  • 251 + 40277 = 40528
  • 359 + 40169 = 40528
  • 401 + 40127 = 40528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40528 first appears in π at position 94,981 of the decimal expansion (the 94,981ordinal-suffix:st 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.
