Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501666, here are decompositions:

  • 43 + 2147501623 = 2147501666
  • 223 + 2147501443 = 2147501666
  • 229 + 2147501437 = 2147501666
  • 433 + 2147501233 = 2147501666
  • 523 + 2147501143 = 2147501666
  • 577 + 2147501089 = 2147501666
  • 757 + 2147500909 = 2147501666
  • 787 + 2147500879 = 2147501666

Showing the first eight; more decompositions exist.
