Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564352, here are decompositions:

19 + 31564333 = 31564352
31 + 31564321 = 31564352
103 + 31564249 = 31564352
109 + 31564243 = 31564352
181 + 31564171 = 31564352
223 + 31564129 = 31564352
373 + 31563979 = 31564352
409 + 31563943 = 31564352

Showing the first eight; more decompositions exist.
