Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497974, here are decompositions:

  • 31 + 2147497943 = 2147497974
  • 53 + 2147497921 = 2147497974
  • 67 + 2147497907 = 2147497974
  • 73 + 2147497901 = 2147497974
  • 241 + 2147497733 = 2147497974
  • 257 + 2147497717 = 2147497974
  • 277 + 2147497697 = 2147497974
  • 283 + 2147497691 = 2147497974

Showing the first eight; more decompositions exist.
