Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40894, here are decompositions:

  • 11 + 40883 = 40894
  • 41 + 40853 = 40894
  • 47 + 40847 = 40894
  • 53 + 40841 = 40894
  • 71 + 40823 = 40894
  • 107 + 40787 = 40894
  • 131 + 40763 = 40894
  • 197 + 40697 = 40894

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40894 first appears in π at position 251,015 of the decimal expansion (the 251,015ordinal-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.
