Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631472, here are decompositions:

  • 71 + 8631401 = 8631472
  • 131 + 8631341 = 8631472
  • 281 + 8631191 = 8631472
  • 389 + 8631083 = 8631472
  • 431 + 8631041 = 8631472
  • 449 + 8631023 = 8631472
  • 461 + 8631011 = 8631472
  • 569 + 8630903 = 8631472

Showing the first eight; more decompositions exist.
