Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147433518, here are decompositions:

  • 31 + 2147433487 = 2147433518
  • 67 + 2147433451 = 2147433518
  • 127 + 2147433391 = 2147433518
  • 271 + 2147433247 = 2147433518
  • 379 + 2147433139 = 2147433518
  • 487 + 2147433031 = 2147433518
  • 751 + 2147432767 = 2147433518
  • 787 + 2147432731 = 2147433518

Showing the first eight; more decompositions exist.
