Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522698, here are decompositions:

  • 5 + 31522693 = 31522698
  • 29 + 31522669 = 31522698
  • 41 + 31522657 = 31522698
  • 101 + 31522597 = 31522698
  • 107 + 31522591 = 31522698
  • 149 + 31522549 = 31522698
  • 157 + 31522541 = 31522698
  • 239 + 31522459 = 31522698

Showing the first eight; more decompositions exist.
