Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563764, here are decompositions:

31 + 31563733 = 31563764
163 + 31563601 = 31563764
313 + 31563451 = 31563764
373 + 31563391 = 31563764
487 + 31563277 = 31563764
571 + 31563193 = 31563764
577 + 31563187 = 31563764
601 + 31563163 = 31563764

Showing the first eight; more decompositions exist.
