Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498392, here are decompositions:

  • 5 + 2147498387 = 2147498392
  • 29 + 2147498363 = 2147498392
  • 59 + 2147498333 = 2147498392
  • 113 + 2147498279 = 2147498392
  • 251 + 2147498141 = 2147498392
  • 359 + 2147498033 = 2147498392
  • 443 + 2147497949 = 2147498392
  • 449 + 2147497943 = 2147498392

Showing the first eight; more decompositions exist.
