Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563362, here are decompositions:

3 + 31563359 = 31563362
13 + 31563349 = 31563362
79 + 31563283 = 31563362
109 + 31563253 = 31563362
199 + 31563163 = 31563362
331 + 31563031 = 31563362
349 + 31563013 = 31563362
379 + 31562983 = 31563362

Showing the first eight; more decompositions exist.
