Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471262, here are decompositions:

  • 139 + 31471123 = 31471262
  • 211 + 31471051 = 31471262
  • 271 + 31470991 = 31471262
  • 349 + 31470913 = 31471262
  • 373 + 31470889 = 31471262
  • 409 + 31470853 = 31471262
  • 439 + 31470823 = 31471262
  • 463 + 31470799 = 31471262

Showing the first eight; more decompositions exist.
