Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742874, here are decompositions:

  • 17 + 8742857 = 8742874
  • 53 + 8742821 = 8742874
  • 197 + 8742677 = 8742874
  • 251 + 8742623 = 8742874
  • 521 + 8742353 = 8742874
  • 557 + 8742317 = 8742874
  • 677 + 8742197 = 8742874
  • 797 + 8742077 = 8742874

Showing the first eight; more decompositions exist.
