Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491218, here are decompositions:

  • 17 + 2147491201 = 2147491218
  • 79 + 2147491139 = 2147491218
  • 107 + 2147491111 = 2147491218
  • 127 + 2147491091 = 2147491218
  • 137 + 2147491081 = 2147491218
  • 149 + 2147491069 = 2147491218
  • 151 + 2147491067 = 2147491218
  • 157 + 2147491061 = 2147491218

Showing the first eight; more decompositions exist.
