Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625514, here are decompositions:

5 + 31625509 = 31625514
7 + 31625507 = 31625514
47 + 31625467 = 31625514
61 + 31625453 = 31625514
83 + 31625431 = 31625514
103 + 31625411 = 31625514
113 + 31625401 = 31625514
131 + 31625383 = 31625514

Showing the first eight; more decompositions exist.
