Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491898, here are decompositions:

  • 61 + 2147491837 = 2147491898
  • 67 + 2147491831 = 2147491898
  • 199 + 2147491699 = 2147491898
  • 421 + 2147491477 = 2147491898
  • 661 + 2147491237 = 2147491898
  • 787 + 2147491111 = 2147491898
  • 829 + 2147491069 = 2147491898
  • 1087 + 2147490811 = 2147491898

Showing the first eight; more decompositions exist.
