Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524494, here are decompositions:

151 + 31524343 = 31524494
163 + 31524331 = 31524494
193 + 31524301 = 31524494
223 + 31524271 = 31524494
271 + 31524223 = 31524494
541 + 31523953 = 31524494
577 + 31523917 = 31524494
613 + 31523881 = 31524494

Showing the first eight; more decompositions exist.
