Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563102, here are decompositions:

13 + 31563089 = 31563102
29 + 31563073 = 31563102
59 + 31563043 = 31563102
61 + 31563041 = 31563102
71 + 31563031 = 31563102
73 + 31563029 = 31563102
89 + 31563013 = 31563102
101 + 31563001 = 31563102

Showing the first eight; more decompositions exist.
