Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17558, here are decompositions:

  • 7 + 17551 = 17558
  • 19 + 17539 = 17558
  • 61 + 17497 = 17558
  • 67 + 17491 = 17558
  • 109 + 17449 = 17558
  • 127 + 17431 = 17558
  • 139 + 17419 = 17558
  • 157 + 17401 = 17558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17558 first appears in π at position 197,295 of the decimal expansion (the 197,295ordinal-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.
