Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7742, here are decompositions:

  • 19 + 7723 = 7742
  • 43 + 7699 = 7742
  • 61 + 7681 = 7742
  • 73 + 7669 = 7742
  • 103 + 7639 = 7742
  • 139 + 7603 = 7742
  • 151 + 7591 = 7742
  • 181 + 7561 = 7742

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7742 first appears in π at position 24,999 of the decimal expansion (the 24,999ordinal-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.
