Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514748, here are decompositions:

7 + 31514741 = 31514748
17 + 31514731 = 31514748
59 + 31514689 = 31514748
61 + 31514687 = 31514748
107 + 31514641 = 31514748
149 + 31514599 = 31514748
197 + 31514551 = 31514748
211 + 31514537 = 31514748

Showing the first eight; more decompositions exist.
