Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514472, here are decompositions:

23 + 31514449 = 31514472
43 + 31514429 = 31514472
53 + 31514419 = 31514472
71 + 31514401 = 31514472
163 + 31514309 = 31514472
181 + 31514291 = 31514472
211 + 31514261 = 31514472
233 + 31514239 = 31514472

Showing the first eight; more decompositions exist.
