Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10428, here are decompositions:

  • 29 + 10399 = 10428
  • 37 + 10391 = 10428
  • 59 + 10369 = 10428
  • 71 + 10357 = 10428
  • 97 + 10331 = 10428
  • 107 + 10321 = 10428
  • 127 + 10301 = 10428
  • 139 + 10289 = 10428

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10428 first appears in π at position 44,773 of the decimal expansion (the 44,773ordinal-suffix:rd 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.
