Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489090, here are decompositions:

  • 3 + 2147489087 = 2147489090
  • 7 + 2147489083 = 2147489090
  • 13 + 2147489077 = 2147489090
  • 31 + 2147489059 = 2147489090
  • 67 + 2147489023 = 2147489090
  • 73 + 2147489017 = 2147489090
  • 223 + 2147488867 = 2147489090
  • 349 + 2147488741 = 2147489090

Showing the first eight; more decompositions exist.
