Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463534, here are decompositions:

7 + 31463527 = 31463534
127 + 31463407 = 31463534
181 + 31463353 = 31463534
307 + 31463227 = 31463534
331 + 31463203 = 31463534
337 + 31463197 = 31463534
367 + 31463167 = 31463534
373 + 31463161 = 31463534

Showing the first eight; more decompositions exist.
