Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522618, here are decompositions:

5 + 31522613 = 31522618
89 + 31522529 = 31522618
167 + 31522451 = 31522618
389 + 31522229 = 31522618
557 + 31522061 = 31522618
599 + 31522019 = 31522618
641 + 31521977 = 31522618
947 + 31521671 = 31522618

Showing the first eight; more decompositions exist.
