Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504962, here are decompositions:

11 + 31504951 = 31504962
19 + 31504943 = 31504962
53 + 31504909 = 31504962
59 + 31504903 = 31504962
79 + 31504883 = 31504962
89 + 31504873 = 31504962
163 + 31504799 = 31504962
179 + 31504783 = 31504962

Showing the first eight; more decompositions exist.
