Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536924, here are decompositions:

7 + 31536917 = 31536924
53 + 31536871 = 31536924
61 + 31536863 = 31536924
101 + 31536823 = 31536924
103 + 31536821 = 31536924
131 + 31536793 = 31536924
151 + 31536773 = 31536924
191 + 31536733 = 31536924

Showing the first eight; more decompositions exist.
