Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563652, here are decompositions:

5 + 31563647 = 31563652
59 + 31563593 = 31563652
83 + 31563569 = 31563652
101 + 31563551 = 31563652
251 + 31563401 = 31563652
293 + 31563359 = 31563652
383 + 31563269 = 31563652
431 + 31563221 = 31563652

Showing the first eight; more decompositions exist.
