Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470186, here are decompositions:

  • 3 + 2147470183 = 2147470186
  • 47 + 2147470139 = 2147470186
  • 167 + 2147470019 = 2147470186
  • 179 + 2147470007 = 2147470186
  • 269 + 2147469917 = 2147470186
  • 557 + 2147469629 = 2147470186
  • 593 + 2147469593 = 2147470186
  • 839 + 2147469347 = 2147470186

Showing the first eight; more decompositions exist.
