Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525194, here are decompositions:

  • 11 + 31525183 = 31525194
  • 17 + 31525177 = 31525194
  • 31 + 31525163 = 31525194
  • 67 + 31525127 = 31525194
  • 73 + 31525121 = 31525194
  • 157 + 31525037 = 31525194
  • 163 + 31525031 = 31525194
  • 167 + 31525027 = 31525194

Showing the first eight; more decompositions exist.
