Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147529782, here are decompositions:

  • 19 + 2147529763 = 2147529782
  • 31 + 2147529751 = 2147529782
  • 109 + 2147529673 = 2147529782
  • 331 + 2147529451 = 2147529782
  • 421 + 2147529361 = 2147529782
  • 631 + 2147529151 = 2147529782
  • 661 + 2147529121 = 2147529782
  • 709 + 2147529073 = 2147529782

Showing the first eight; more decompositions exist.
