Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514568, here are decompositions:

17 + 31514551 = 31514568
31 + 31514537 = 31514568
89 + 31514479 = 31514568
139 + 31514429 = 31514568
149 + 31514419 = 31514568
167 + 31514401 = 31514568
271 + 31514297 = 31514568
277 + 31514291 = 31514568

Showing the first eight; more decompositions exist.
