Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463358, here are decompositions:

5 + 31463353 = 31463358
29 + 31463329 = 31463358
37 + 31463321 = 31463358
41 + 31463317 = 31463358
89 + 31463269 = 31463358
97 + 31463261 = 31463358
109 + 31463249 = 31463358
131 + 31463227 = 31463358

Showing the first eight; more decompositions exist.
