Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147505104, here are decompositions:

  • 67 + 2147505037 = 2147505104
  • 127 + 2147504977 = 2147505104
  • 193 + 2147504911 = 2147505104
  • 373 + 2147504731 = 2147505104
  • 457 + 2147504647 = 2147505104
  • 727 + 2147504377 = 2147505104
  • 757 + 2147504347 = 2147505104
  • 991 + 2147504113 = 2147505104

Showing the first eight; more decompositions exist.
