Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147556266, here are decompositions:

  • 19 + 2147556247 = 2147556266
  • 127 + 2147556139 = 2147556266
  • 199 + 2147556067 = 2147556266
  • 223 + 2147556043 = 2147556266
  • 277 + 2147555989 = 2147556266
  • 337 + 2147555929 = 2147556266
  • 367 + 2147555899 = 2147556266
  • 397 + 2147555869 = 2147556266

Showing the first eight; more decompositions exist.
