Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500738, here are decompositions:

  • 41 + 2147500697 = 2147500738
  • 179 + 2147500559 = 2147500738
  • 239 + 2147500499 = 2147500738
  • 479 + 2147500259 = 2147500738
  • 491 + 2147500247 = 2147500738
  • 599 + 2147500139 = 2147500738
  • 821 + 2147499917 = 2147500738
  • 1031 + 2147499707 = 2147500738

Showing the first eight; more decompositions exist.
