Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500842, here are decompositions:

  • 29 + 2147500813 = 2147500842
  • 61 + 2147500781 = 2147500842
  • 79 + 2147500763 = 2147500842
  • 181 + 2147500661 = 2147500842
  • 229 + 2147500613 = 2147500842
  • 251 + 2147500591 = 2147500842
  • 281 + 2147500561 = 2147500842
  • 283 + 2147500559 = 2147500842

Showing the first eight; more decompositions exist.
