Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497818, here are decompositions:

  • 47 + 2147497771 = 2147497818
  • 61 + 2147497757 = 2147497818
  • 101 + 2147497717 = 2147497818
  • 127 + 2147497691 = 2147497818
  • 157 + 2147497661 = 2147497818
  • 311 + 2147497507 = 2147497818
  • 337 + 2147497481 = 2147497818
  • 359 + 2147497459 = 2147497818

Showing the first eight; more decompositions exist.
