Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57978, here are decompositions:

  • 5 + 57973 = 57978
  • 31 + 57947 = 57978
  • 61 + 57917 = 57978
  • 79 + 57899 = 57978
  • 97 + 57881 = 57978
  • 131 + 57847 = 57978
  • 139 + 57839 = 57978
  • 149 + 57829 = 57978

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 57978 first appears in π at position 4,138 of the decimal expansion (the 4,138ordinal-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.
