Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535186, here are decompositions:

  • 3 + 31535183 = 31535186
  • 13 + 31535173 = 31535186
  • 43 + 31535143 = 31535186
  • 73 + 31535113 = 31535186
  • 79 + 31535107 = 31535186
  • 103 + 31535083 = 31535186
  • 127 + 31535059 = 31535186
  • 307 + 31534879 = 31535186

Showing the first eight; more decompositions exist.
