Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463310, here are decompositions:

29 + 31463281 = 31463310
41 + 31463269 = 31463310
61 + 31463249 = 31463310
83 + 31463227 = 31463310
97 + 31463213 = 31463310
107 + 31463203 = 31463310
113 + 31463197 = 31463310
149 + 31463161 = 31463310

Showing the first eight; more decompositions exist.
