Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743990, here are decompositions:

  • 53 + 8743937 = 8743990
  • 71 + 8743919 = 8743990
  • 89 + 8743901 = 8743990
  • 107 + 8743883 = 8743990
  • 137 + 8743853 = 8743990
  • 173 + 8743817 = 8743990
  • 257 + 8743733 = 8743990
  • 317 + 8743673 = 8743990

Showing the first eight; more decompositions exist.
