Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481276, here are decompositions:

  • 7 + 2147481269 = 2147481276
  • 13 + 2147481263 = 2147481276
  • 29 + 2147481247 = 2147481276
  • 67 + 2147481209 = 2147481276
  • 97 + 2147481179 = 2147481276
  • 103 + 2147481173 = 2147481276
  • 137 + 2147481139 = 2147481276
  • 223 + 2147481053 = 2147481276

Showing the first eight; more decompositions exist.
