Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7826, here are decompositions:

  • 3 + 7823 = 7826
  • 37 + 7789 = 7826
  • 67 + 7759 = 7826
  • 73 + 7753 = 7826
  • 103 + 7723 = 7826
  • 109 + 7717 = 7826
  • 127 + 7699 = 7826
  • 139 + 7687 = 7826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7826 first appears in π at position 2,057 of the decimal expansion (the 2,057ordinal-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.
