Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463394, here are decompositions:

5 + 31463389 = 31463394
7 + 31463387 = 31463394
31 + 31463363 = 31463394
41 + 31463353 = 31463394
73 + 31463321 = 31463394
113 + 31463281 = 31463394
167 + 31463227 = 31463394
181 + 31463213 = 31463394

Showing the first eight; more decompositions exist.
