Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535370, here are decompositions:

  • 29 + 31535341 = 31535370
  • 43 + 31535327 = 31535370
  • 59 + 31535311 = 31535370
  • 107 + 31535263 = 31535370
  • 137 + 31535233 = 31535370
  • 151 + 31535219 = 31535370
  • 157 + 31535213 = 31535370
  • 197 + 31535173 = 31535370

Showing the first eight; more decompositions exist.
