Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463312, here are decompositions:

31 + 31463281 = 31463312
43 + 31463269 = 31463312
109 + 31463203 = 31463312
151 + 31463161 = 31463312
229 + 31463083 = 31463312
379 + 31462933 = 31463312
541 + 31462771 = 31463312
709 + 31462603 = 31463312

Showing the first eight; more decompositions exist.
