Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563534, here are decompositions:

7 + 31563527 = 31563534
43 + 31563491 = 31563534
71 + 31563463 = 31563534
83 + 31563451 = 31563534
103 + 31563431 = 31563534
131 + 31563403 = 31563534
157 + 31563377 = 31563534
251 + 31563283 = 31563534

Showing the first eight; more decompositions exist.
