Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1402, here are decompositions:

  • 3 + 1399 = 1402
  • 29 + 1373 = 1402
  • 41 + 1361 = 1402
  • 83 + 1319 = 1402
  • 101 + 1301 = 1402
  • 113 + 1289 = 1402
  • 173 + 1229 = 1402
  • 179 + 1223 = 1402

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1402 first appears in π at position 4,538 of the decimal expansion (the 4,538ordinal-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.
