Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508128, here are decompositions:

31 + 508097 = 508128
37 + 508091 = 508128
41 + 508087 = 508128
107 + 508021 = 508128
109 + 508019 = 508128
149 + 507979 = 508128
157 + 507971 = 508128
167 + 507961 = 508128

Showing the first eight; more decompositions exist.
