Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497826, here are decompositions:

  • 109 + 2147497717 = 2147497826
  • 127 + 2147497699 = 2147497826
  • 163 + 2147497663 = 2147497826
  • 337 + 2147497489 = 2147497826
  • 367 + 2147497459 = 2147497826
  • 379 + 2147497447 = 2147497826
  • 433 + 2147497393 = 2147497826
  • 787 + 2147497039 = 2147497826

Showing the first eight; more decompositions exist.
