Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469818, here are decompositions:

  • 37 + 2147469781 = 2147469818
  • 139 + 2147469679 = 2147469818
  • 181 + 2147469637 = 2147469818
  • 199 + 2147469619 = 2147469818
  • 397 + 2147469421 = 2147469818
  • 547 + 2147469271 = 2147469818
  • 631 + 2147469187 = 2147469818
  • 661 + 2147469157 = 2147469818

Showing the first eight; more decompositions exist.
