Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490666, here are decompositions:

  • 7 + 2147490659 = 2147490666
  • 73 + 2147490593 = 2147490666
  • 89 + 2147490577 = 2147490666
  • 109 + 2147490557 = 2147490666
  • 127 + 2147490539 = 2147490666
  • 137 + 2147490529 = 2147490666
  • 179 + 2147490487 = 2147490666
  • 383 + 2147490283 = 2147490666

Showing the first eight; more decompositions exist.
