Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497698, here are decompositions:

  • 7 + 2147497691 = 2147497698
  • 37 + 2147497661 = 2147497698
  • 127 + 2147497571 = 2147497698
  • 139 + 2147497559 = 2147497698
  • 191 + 2147497507 = 2147497698
  • 239 + 2147497459 = 2147497698
  • 251 + 2147497447 = 2147497698
  • 337 + 2147497361 = 2147497698

Showing the first eight; more decompositions exist.
