Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467844, here are decompositions:

  • 31 + 2147467813 = 2147467844
  • 43 + 2147467801 = 2147467844
  • 97 + 2147467747 = 2147467844
  • 127 + 2147467717 = 2147467844
  • 373 + 2147467471 = 2147467844
  • 523 + 2147467321 = 2147467844
  • 751 + 2147467093 = 2147467844
  • 787 + 2147467057 = 2147467844

Showing the first eight; more decompositions exist.
