Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147536658, here are decompositions:

  • 67 + 2147536591 = 2147536658
  • 199 + 2147536459 = 2147536658
  • 457 + 2147536201 = 2147536658
  • 577 + 2147536081 = 2147536658
  • 607 + 2147536051 = 2147536658
  • 811 + 2147535847 = 2147536658
  • 907 + 2147535751 = 2147536658
  • 919 + 2147535739 = 2147536658

Showing the first eight; more decompositions exist.
