Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147462782, here are decompositions:

  • 29 + 2147462753 = 2147462782
  • 89 + 2147462693 = 2147462782
  • 149 + 2147462633 = 2147462782
  • 239 + 2147462543 = 2147462782
  • 389 + 2147462393 = 2147462782
  • 401 + 2147462381 = 2147462782
  • 593 + 2147462189 = 2147462782
  • 659 + 2147462123 = 2147462782

Showing the first eight; more decompositions exist.
