Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491040, here are decompositions:

  • 3 + 2147491037 = 2147491040
  • 7 + 2147491033 = 2147491040
  • 43 + 2147490997 = 2147491040
  • 67 + 2147490973 = 2147491040
  • 73 + 2147490967 = 2147491040
  • 157 + 2147490883 = 2147491040
  • 229 + 2147490811 = 2147491040
  • 241 + 2147490799 = 2147491040

Showing the first eight; more decompositions exist.
