Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504008, here are decompositions:

  • 31 + 31503977 = 31504008
  • 37 + 31503971 = 31504008
  • 47 + 31503961 = 31504008
  • 79 + 31503929 = 31504008
  • 97 + 31503911 = 31504008
  • 167 + 31503841 = 31504008
  • 197 + 31503811 = 31504008
  • 199 + 31503809 = 31504008

Showing the first eight; more decompositions exist.
