Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497732, here are decompositions:

  • 41 + 2147497691 = 2147497732
  • 71 + 2147497661 = 2147497732
  • 173 + 2147497559 = 2147497732
  • 239 + 2147497493 = 2147497732
  • 251 + 2147497481 = 2147497732
  • 383 + 2147497349 = 2147497732
  • 599 + 2147497133 = 2147497732
  • 761 + 2147496971 = 2147497732

Showing the first eight; more decompositions exist.
