Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468228, here are decompositions:

  • 97 + 2147468131 = 2147468228
  • 109 + 2147468119 = 2147468228
  • 307 + 2147467921 = 2147468228
  • 601 + 2147467627 = 2147468228
  • 757 + 2147467471 = 2147468228
  • 907 + 2147467321 = 2147468228
  • 967 + 2147467261 = 2147468228
  • 1009 + 2147467219 = 2147468228

Showing the first eight; more decompositions exist.
