Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491142, here are decompositions:

  • 3 + 2147491139 = 2147491142
  • 19 + 2147491123 = 2147491142
  • 31 + 2147491111 = 2147491142
  • 61 + 2147491081 = 2147491142
  • 73 + 2147491069 = 2147491142
  • 109 + 2147491033 = 2147491142
  • 271 + 2147490871 = 2147491142
  • 331 + 2147490811 = 2147491142

Showing the first eight; more decompositions exist.
