Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564262, here are decompositions:

13 + 31564249 = 31564262
19 + 31564243 = 31564262
211 + 31564051 = 31564262
283 + 31563979 = 31564262
313 + 31563949 = 31564262
661 + 31563601 = 31564262
811 + 31563451 = 31564262
859 + 31563403 = 31564262

Showing the first eight; more decompositions exist.
