Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505964, here are decompositions:

5 + 31505959 = 31505964
37 + 31505927 = 31505964
41 + 31505923 = 31505964
43 + 31505921 = 31505964
151 + 31505813 = 31505964
157 + 31505807 = 31505964
163 + 31505801 = 31505964
181 + 31505783 = 31505964

Showing the first eight; more decompositions exist.
