Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7946, here are decompositions:

  • 13 + 7933 = 7946
  • 19 + 7927 = 7946
  • 67 + 7879 = 7946
  • 73 + 7873 = 7946
  • 79 + 7867 = 7946
  • 157 + 7789 = 7946
  • 193 + 7753 = 7946
  • 223 + 7723 = 7946

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7946 first appears in π at position 7,229 of the decimal expansion (the 7,229ordinal-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.
