Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463682, here are decompositions:

149 + 31463533 = 31463682
163 + 31463519 = 31463682
193 + 31463489 = 31463682
199 + 31463483 = 31463682
223 + 31463459 = 31463682
293 + 31463389 = 31463682
353 + 31463329 = 31463682
401 + 31463281 = 31463682

Showing the first eight; more decompositions exist.
