Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147557822, here are decompositions:

  • 149 + 2147557673 = 2147557822
  • 359 + 2147557463 = 2147557822
  • 461 + 2147557361 = 2147557822
  • 491 + 2147557331 = 2147557822
  • 521 + 2147557301 = 2147557822
  • 701 + 2147557121 = 2147557822
  • 863 + 2147556959 = 2147557822
  • 929 + 2147556893 = 2147557822

Showing the first eight; more decompositions exist.
