Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497786, here are decompositions:

  • 17 + 2147497769 = 2147497786
  • 29 + 2147497757 = 2147497786
  • 53 + 2147497733 = 2147497786
  • 89 + 2147497697 = 2147497786
  • 227 + 2147497559 = 2147497786
  • 263 + 2147497523 = 2147497786
  • 293 + 2147497493 = 2147497786
  • 383 + 2147497403 = 2147497786

Showing the first eight; more decompositions exist.
