Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563654, here are decompositions:

7 + 31563647 = 31563654
53 + 31563601 = 31563654
61 + 31563593 = 31563654
103 + 31563551 = 31563654
127 + 31563527 = 31563654
163 + 31563491 = 31563654
191 + 31563463 = 31563654
211 + 31563443 = 31563654

Showing the first eight; more decompositions exist.
