Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528038, here are decompositions:

19 + 31528019 = 31528038
37 + 31528001 = 31528038
41 + 31527997 = 31528038
71 + 31527967 = 31528038
97 + 31527941 = 31528038
107 + 31527931 = 31528038
151 + 31527887 = 31528038
211 + 31527827 = 31528038

Showing the first eight; more decompositions exist.
