Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463492, here are decompositions:

3 + 31463489 = 31463492
103 + 31463389 = 31463492
139 + 31463353 = 31463492
163 + 31463329 = 31463492
211 + 31463281 = 31463492
223 + 31463269 = 31463492
331 + 31463161 = 31463492
409 + 31463083 = 31463492

Showing the first eight; more decompositions exist.
