Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51078, here are decompositions:

  • 7 + 51071 = 51078
  • 17 + 51061 = 51078
  • 19 + 51059 = 51078
  • 31 + 51047 = 51078
  • 47 + 51031 = 51078
  • 89 + 50989 = 51078
  • 107 + 50971 = 51078
  • 109 + 50969 = 51078

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51078 first appears in π at position 99,728 of the decimal expansion (the 99,728ordinal-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.
