Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564024, here are decompositions:

71 + 31563953 = 31564024
83 + 31563941 = 31564024
113 + 31563911 = 31564024
197 + 31563827 = 31564024
251 + 31563773 = 31564024
353 + 31563671 = 31564024
431 + 31563593 = 31564024
593 + 31563431 = 31564024

Showing the first eight; more decompositions exist.
