Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74978, here are decompositions:

  • 19 + 74959 = 74978
  • 37 + 74941 = 74978
  • 109 + 74869 = 74978
  • 151 + 74827 = 74978
  • 157 + 74821 = 74978
  • 181 + 74797 = 74978
  • 199 + 74779 = 74978
  • 271 + 74707 = 74978

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 74978 first appears in π at position 22,575 of the decimal expansion (the 22,575ordinal-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.
