Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467144, here are decompositions:

  • 23 + 2147467121 = 2147467144
  • 101 + 2147467043 = 2147467144
  • 197 + 2147466947 = 2147467144
  • 311 + 2147466833 = 2147467144
  • 443 + 2147466701 = 2147467144
  • 461 + 2147466683 = 2147467144
  • 503 + 2147466641 = 2147467144
  • 761 + 2147466383 = 2147467144

Showing the first eight; more decompositions exist.
