Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486990, here are decompositions:

  • 139 + 2147486851 = 2147486990
  • 163 + 2147486827 = 2147486990
  • 199 + 2147486791 = 2147486990
  • 241 + 2147486749 = 2147486990
  • 283 + 2147486707 = 2147486990
  • 349 + 2147486641 = 2147486990
  • 373 + 2147486617 = 2147486990
  • 433 + 2147486557 = 2147486990

Showing the first eight; more decompositions exist.
