Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463208, here are decompositions:

  • 5 + 31463203 = 31463208
  • 11 + 31463197 = 31463208
  • 41 + 31463167 = 31463208
  • 47 + 31463161 = 31463208
  • 61 + 31463147 = 31463208
  • 71 + 31463137 = 31463208
  • 109 + 31463099 = 31463208
  • 131 + 31463077 = 31463208

Showing the first eight; more decompositions exist.
