Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546372, here are decompositions:

  • 3 + 31546369 = 31546372
  • 23 + 31546349 = 31546372
  • 71 + 31546301 = 31546372
  • 89 + 31546283 = 31546372
  • 173 + 31546199 = 31546372
  • 191 + 31546181 = 31546372
  • 353 + 31546019 = 31546372
  • 359 + 31546013 = 31546372

Showing the first eight; more decompositions exist.
