Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524850, here are decompositions:

  • 11 + 31524839 = 31524850
  • 41 + 31524809 = 31524850
  • 53 + 31524797 = 31524850
  • 59 + 31524791 = 31524850
  • 83 + 31524767 = 31524850
  • 173 + 31524677 = 31524850
  • 263 + 31524587 = 31524850
  • 281 + 31524569 = 31524850

Showing the first eight; more decompositions exist.
