Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463466, here are decompositions:

7 + 31463459 = 31463466
37 + 31463429 = 31463466
59 + 31463407 = 31463466
79 + 31463387 = 31463466
103 + 31463363 = 31463466
113 + 31463353 = 31463466
137 + 31463329 = 31463466
149 + 31463317 = 31463466

Showing the first eight; more decompositions exist.
