Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2606, here are decompositions:

  • 13 + 2593 = 2606
  • 67 + 2539 = 2606
  • 103 + 2503 = 2606
  • 139 + 2467 = 2606
  • 223 + 2383 = 2606
  • 229 + 2377 = 2606
  • 313 + 2293 = 2606
  • 337 + 2269 = 2606

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2606 first appears in π at position 5,561 of the decimal expansion (the 5,561ordinal-suffix:st 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.
