Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16398, here are decompositions:

  • 17 + 16381 = 16398
  • 29 + 16369 = 16398
  • 37 + 16361 = 16398
  • 59 + 16339 = 16398
  • 79 + 16319 = 16398
  • 97 + 16301 = 16398
  • 131 + 16267 = 16398
  • 149 + 16249 = 16398

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16398 first appears in π at position 3,516 of the decimal expansion (the 3,516ordinal-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.
