Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563060, here are decompositions:

17 + 31563043 = 31563060
19 + 31563041 = 31563060
29 + 31563031 = 31563060
31 + 31563029 = 31563060
47 + 31563013 = 31563060
59 + 31563001 = 31563060
73 + 31562987 = 31563060
79 + 31562981 = 31563060

Showing the first eight; more decompositions exist.
