Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514940, here are decompositions:

  • 7 + 31514933 = 31514940
  • 29 + 31514911 = 31514940
  • 47 + 31514893 = 31514940
  • 71 + 31514869 = 31514940
  • 101 + 31514839 = 31514940
  • 103 + 31514837 = 31514940
  • 151 + 31514789 = 31514940
  • 157 + 31514783 = 31514940

Showing the first eight; more decompositions exist.
