Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512058, here are decompositions:

41 + 31512017 = 31512058
47 + 31512011 = 31512058
89 + 31511969 = 31512058
131 + 31511927 = 31512058
167 + 31511891 = 31512058
191 + 31511867 = 31512058
257 + 31511801 = 31512058
509 + 31511549 = 31512058

Showing the first eight; more decompositions exist.
