Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514628, here are decompositions:

29 + 31514599 = 31514628
149 + 31514479 = 31514628
151 + 31514477 = 31514628
179 + 31514449 = 31514628
199 + 31514429 = 31514628
227 + 31514401 = 31514628
331 + 31514297 = 31514628
337 + 31514291 = 31514628

Showing the first eight; more decompositions exist.
