Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487146, here are decompositions:

  • 97 + 2147487049 = 2147487146
  • 397 + 2147486749 = 2147487146
  • 439 + 2147486707 = 2147487146
  • 457 + 2147486689 = 2147487146
  • 547 + 2147486599 = 2147487146
  • 619 + 2147486527 = 2147487146
  • 733 + 2147486413 = 2147487146
  • 829 + 2147486317 = 2147487146

Showing the first eight; more decompositions exist.
