Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532436, here are decompositions:

  • 7 + 31532429 = 31532436
  • 83 + 31532353 = 31532436
  • 97 + 31532339 = 31532436
  • 107 + 31532329 = 31532436
  • 113 + 31532323 = 31532436
  • 157 + 31532279 = 31532436
  • 167 + 31532269 = 31532436
  • 227 + 31532209 = 31532436

Showing the first eight; more decompositions exist.
