Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463546, here are decompositions:

13 + 31463533 = 31463546
19 + 31463527 = 31463546
139 + 31463407 = 31463546
157 + 31463389 = 31463546
193 + 31463353 = 31463546
229 + 31463317 = 31463546
277 + 31463269 = 31463546
349 + 31463197 = 31463546

Showing the first eight; more decompositions exist.
