Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16402, here are decompositions:

  • 41 + 16361 = 16402
  • 53 + 16349 = 16402
  • 83 + 16319 = 16402
  • 101 + 16301 = 16402
  • 149 + 16253 = 16402
  • 173 + 16229 = 16402
  • 179 + 16223 = 16402
  • 263 + 16139 = 16402

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16402 first appears in π at position 351,119 of the decimal expansion (the 351,119ordinal-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.
