Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487170, here are decompositions:

  • 13 + 2147487157 = 2147487170
  • 313 + 2147486857 = 2147487170
  • 379 + 2147486791 = 2147487170
  • 421 + 2147486749 = 2147487170
  • 463 + 2147486707 = 2147487170
  • 571 + 2147486599 = 2147487170
  • 613 + 2147486557 = 2147487170
  • 643 + 2147486527 = 2147487170

Showing the first eight; more decompositions exist.
