Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588652, here are decompositions:

  • 5 + 2147588647 = 2147588652
  • 31 + 2147588621 = 2147588652
  • 43 + 2147588609 = 2147588652
  • 59 + 2147588593 = 2147588652
  • 103 + 2147588549 = 2147588652
  • 109 + 2147588543 = 2147588652
  • 113 + 2147588539 = 2147588652
  • 151 + 2147588501 = 2147588652

Showing the first eight; more decompositions exist.
