Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525368, here are decompositions:

  • 37 + 31525331 = 31525368
  • 79 + 31525289 = 31525368
  • 89 + 31525279 = 31525368
  • 101 + 31525267 = 31525368
  • 107 + 31525261 = 31525368
  • 139 + 31525229 = 31525368
  • 157 + 31525211 = 31525368
  • 167 + 31525201 = 31525368

Showing the first eight; more decompositions exist.
