Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399700, here are decompositions:

  • 11 + 2147399689 = 2147399700
  • 29 + 2147399671 = 2147399700
  • 37 + 2147399663 = 2147399700
  • 71 + 2147399629 = 2147399700
  • 97 + 2147399603 = 2147399700
  • 107 + 2147399593 = 2147399700
  • 113 + 2147399587 = 2147399700
  • 139 + 2147399561 = 2147399700

Showing the first eight; more decompositions exist.
