Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528210, here are decompositions:

  • 3 + 31528207 = 31528210
  • 41 + 31528169 = 31528210
  • 53 + 31528157 = 31528210
  • 59 + 31528151 = 31528210
  • 83 + 31528127 = 31528210
  • 89 + 31528121 = 31528210
  • 107 + 31528103 = 31528210
  • 173 + 31528037 = 31528210

Showing the first eight; more decompositions exist.
