Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147461982, here are decompositions:

  • 139 + 2147461843 = 2147461982
  • 199 + 2147461783 = 2147461982
  • 331 + 2147461651 = 2147461982
  • 499 + 2147461483 = 2147461982
  • 619 + 2147461363 = 2147461982
  • 709 + 2147461273 = 2147461982
  • 1063 + 2147460919 = 2147461982
  • 1153 + 2147460829 = 2147461982

Showing the first eight; more decompositions exist.
