Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446876, here are decompositions:

  • 5 + 31446871 = 31446876
  • 17 + 31446859 = 31446876
  • 23 + 31446853 = 31446876
  • 29 + 31446847 = 31446876
  • 37 + 31446839 = 31446876
  • 107 + 31446769 = 31446876
  • 127 + 31446749 = 31446876
  • 137 + 31446739 = 31446876

Showing the first eight; more decompositions exist.
