Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580252, here are decompositions:

  • 13 + 31580239 = 31580252
  • 19 + 31580233 = 31580252
  • 31 + 31580221 = 31580252
  • 103 + 31580149 = 31580252
  • 139 + 31580113 = 31580252
  • 199 + 31580053 = 31580252
  • 283 + 31579969 = 31580252
  • 421 + 31579831 = 31580252

Showing the first eight; more decompositions exist.
