Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469860, here are decompositions:

  • 31 + 2147469829 = 2147469860
  • 37 + 2147469823 = 2147469860
  • 43 + 2147469817 = 2147469860
  • 79 + 2147469781 = 2147469860
  • 157 + 2147469703 = 2147469860
  • 181 + 2147469679 = 2147469860
  • 223 + 2147469637 = 2147469860
  • 241 + 2147469619 = 2147469860

Showing the first eight; more decompositions exist.
