Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454312, here are decompositions:

151 + 31454161 = 31454312
163 + 31454149 = 31454312
229 + 31454083 = 31454312
433 + 31453879 = 31454312
499 + 31453813 = 31454312
601 + 31453711 = 31454312
613 + 31453699 = 31454312
661 + 31453651 = 31454312

Showing the first eight; more decompositions exist.
