Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469608, here are decompositions:

  • 337 + 2147469271 = 2147469608
  • 379 + 2147469229 = 2147469608
  • 421 + 2147469187 = 2147469608
  • 541 + 2147469067 = 2147469608
  • 601 + 2147469007 = 2147469608
  • 607 + 2147469001 = 2147469608
  • 727 + 2147468881 = 2147469608
  • 829 + 2147468779 = 2147469608

Showing the first eight; more decompositions exist.
