Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631744, here are decompositions:

  • 7 + 8631737 = 8631744
  • 31 + 8631713 = 8631744
  • 71 + 8631673 = 8631744
  • 127 + 8631617 = 8631744
  • 211 + 8631533 = 8631744
  • 227 + 8631517 = 8631744
  • 293 + 8631451 = 8631744
  • 353 + 8631391 = 8631744

Showing the first eight; more decompositions exist.
