Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527186, here are decompositions:

  • 13 + 31527173 = 31527186
  • 29 + 31527157 = 31527186
  • 37 + 31527149 = 31527186
  • 43 + 31527143 = 31527186
  • 79 + 31527107 = 31527186
  • 109 + 31527077 = 31527186
  • 139 + 31527047 = 31527186
  • 233 + 31526953 = 31527186

Showing the first eight; more decompositions exist.
