Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525042, here are decompositions:

  • 5 + 31525037 = 31525042
  • 11 + 31525031 = 31525042
  • 53 + 31524989 = 31525042
  • 149 + 31524893 = 31525042
  • 179 + 31524863 = 31525042
  • 233 + 31524809 = 31525042
  • 251 + 31524791 = 31525042
  • 401 + 31524641 = 31525042

Showing the first eight; more decompositions exist.
