Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10442, here are decompositions:

  • 13 + 10429 = 10442
  • 43 + 10399 = 10442
  • 73 + 10369 = 10442
  • 109 + 10333 = 10442
  • 139 + 10303 = 10442
  • 199 + 10243 = 10442
  • 283 + 10159 = 10442
  • 331 + 10111 = 10442

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10442 first appears in π at position 132,324 of the decimal expansion (the 132,324ordinal-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.
