Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463846, here are decompositions:

3 + 31463843 = 31463846
19 + 31463827 = 31463846
67 + 31463779 = 31463846
79 + 31463767 = 31463846
103 + 31463743 = 31463846
157 + 31463689 = 31463846
313 + 31463533 = 31463846
439 + 31463407 = 31463846

Showing the first eight; more decompositions exist.
