Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500894, here are decompositions:

  • 5 + 2147500889 = 2147500894
  • 23 + 2147500871 = 2147500894
  • 113 + 2147500781 = 2147500894
  • 131 + 2147500763 = 2147500894
  • 197 + 2147500697 = 2147500894
  • 233 + 2147500661 = 2147500894
  • 281 + 2147500613 = 2147500894
  • 401 + 2147500493 = 2147500894

Showing the first eight; more decompositions exist.
