Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470198, here are decompositions:

  • 59 + 2147470139 = 2147470198
  • 131 + 2147470067 = 2147470198
  • 179 + 2147470019 = 2147470198
  • 191 + 2147470007 = 2147470198
  • 281 + 2147469917 = 2147470198
  • 317 + 2147469881 = 2147470198
  • 569 + 2147469629 = 2147470198
  • 677 + 2147469521 = 2147470198

Showing the first eight; more decompositions exist.
