Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514668, here are decompositions:

5 + 31514663 = 31514668
41 + 31514627 = 31514668
89 + 31514579 = 31514668
131 + 31514537 = 31514668
191 + 31514477 = 31514668
239 + 31514429 = 31514668
359 + 31514309 = 31514668
401 + 31514267 = 31514668

Showing the first eight; more decompositions exist.
