Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742286, here are decompositions:

  • 23 + 8742263 = 8742286
  • 89 + 8742197 = 8742286
  • 227 + 8742059 = 8742286
  • 353 + 8741933 = 8742286
  • 419 + 8741867 = 8742286
  • 587 + 8741699 = 8742286
  • 599 + 8741687 = 8742286
  • 647 + 8741639 = 8742286

Showing the first eight; more decompositions exist.
