Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45428, here are decompositions:

  • 67 + 45361 = 45428
  • 109 + 45319 = 45428
  • 139 + 45289 = 45428
  • 181 + 45247 = 45428
  • 307 + 45121 = 45428
  • 367 + 45061 = 45428
  • 421 + 45007 = 45428
  • 457 + 44971 = 45428

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45428 first appears in π at position 2,700 of the decimal expansion (the 2,700ordinal-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.
