Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448900, here are decompositions:

  • 13 + 2147448887 = 2147448900
  • 19 + 2147448881 = 2147448900
  • 137 + 2147448763 = 2147448900
  • 151 + 2147448749 = 2147448900
  • 167 + 2147448733 = 2147448900
  • 193 + 2147448707 = 2147448900
  • 197 + 2147448703 = 2147448900
  • 199 + 2147448701 = 2147448900

Showing the first eight; more decompositions exist.
