Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399750, here are decompositions:

  • 19 + 2147399731 = 2147399750
  • 31 + 2147399719 = 2147399750
  • 61 + 2147399689 = 2147399750
  • 79 + 2147399671 = 2147399750
  • 157 + 2147399593 = 2147399750
  • 163 + 2147399587 = 2147399750
  • 229 + 2147399521 = 2147399750
  • 241 + 2147399509 = 2147399750

Showing the first eight; more decompositions exist.
