Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447026, here are decompositions:

  • 5 + 31447021 = 31447026
  • 7 + 31447019 = 31447026
  • 29 + 31446997 = 31447026
  • 43 + 31446983 = 31447026
  • 53 + 31446973 = 31447026
  • 73 + 31446953 = 31447026
  • 89 + 31446937 = 31447026
  • 109 + 31446917 = 31447026

Showing the first eight; more decompositions exist.
