Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7718, here are decompositions:

  • 19 + 7699 = 7718
  • 31 + 7687 = 7718
  • 37 + 7681 = 7718
  • 79 + 7639 = 7718
  • 97 + 7621 = 7718
  • 127 + 7591 = 7718
  • 157 + 7561 = 7718
  • 181 + 7537 = 7718

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7718 first appears in π at position 4,143 of the decimal expansion (the 4,143ordinal-suffix:rd 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.
