Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16510, here are decompositions:

  • 17 + 16493 = 16510
  • 23 + 16487 = 16510
  • 29 + 16481 = 16510
  • 59 + 16451 = 16510
  • 83 + 16427 = 16510
  • 89 + 16421 = 16510
  • 149 + 16361 = 16510
  • 191 + 16319 = 16510

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16510 first appears in π at position 28,939 of the decimal expansion (the 28,939ordinal-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.
