Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505716, here are decompositions:

23 + 31505693 = 31505716
59 + 31505657 = 31505716
83 + 31505633 = 31505716
107 + 31505609 = 31505716
149 + 31505567 = 31505716
197 + 31505519 = 31505716
227 + 31505489 = 31505716
257 + 31505459 = 31505716

Showing the first eight; more decompositions exist.
