Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463258, here are decompositions:

31 + 31463227 = 31463258
61 + 31463197 = 31463258
97 + 31463161 = 31463258
181 + 31463077 = 31463258
349 + 31462909 = 31463258
487 + 31462771 = 31463258
499 + 31462759 = 31463258
727 + 31462531 = 31463258

Showing the first eight; more decompositions exist.
