Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514634, here are decompositions:

5 + 31514629 = 31514634
7 + 31514627 = 31514634
61 + 31514573 = 31514634
83 + 31514551 = 31514634
97 + 31514537 = 31514634
101 + 31514533 = 31514634
157 + 31514477 = 31514634
211 + 31514423 = 31514634

Showing the first eight; more decompositions exist.
