Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563852, here are decompositions:

59 + 31563793 = 31563852
79 + 31563773 = 31563852
181 + 31563671 = 31563852
251 + 31563601 = 31563852
283 + 31563569 = 31563852
389 + 31563463 = 31563852
401 + 31563451 = 31563852
409 + 31563443 = 31563852

Showing the first eight; more decompositions exist.
