Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467748, here are decompositions:

  • 31 + 2147467717 = 2147467748
  • 37 + 2147467711 = 2147467748
  • 79 + 2147467669 = 2147467748
  • 109 + 2147467639 = 2147467748
  • 277 + 2147467471 = 2147467748
  • 409 + 2147467339 = 2147467748
  • 421 + 2147467327 = 2147467748
  • 487 + 2147467261 = 2147467748

Showing the first eight; more decompositions exist.
