Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500732, here are decompositions:

  • 71 + 2147500661 = 2147500732
  • 173 + 2147500559 = 2147500732
  • 233 + 2147500499 = 2147500732
  • 239 + 2147500493 = 2147500732
  • 389 + 2147500343 = 2147500732
  • 431 + 2147500301 = 2147500732
  • 491 + 2147500241 = 2147500732
  • 593 + 2147500139 = 2147500732

Showing the first eight; more decompositions exist.
