Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498464, here are decompositions:

  • 71 + 2147498393 = 2147498464
  • 101 + 2147498363 = 2147498464
  • 131 + 2147498333 = 2147498464
  • 317 + 2147498147 = 2147498464
  • 347 + 2147498117 = 2147498464
  • 431 + 2147498033 = 2147498464
  • 521 + 2147497943 = 2147498464
  • 557 + 2147497907 = 2147498464

Showing the first eight; more decompositions exist.
