Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463354, here are decompositions:

37 + 31463317 = 31463354
73 + 31463281 = 31463354
127 + 31463227 = 31463354
151 + 31463203 = 31463354
157 + 31463197 = 31463354
193 + 31463161 = 31463354
271 + 31463083 = 31463354
277 + 31463077 = 31463354

Showing the first eight; more decompositions exist.
