Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523038, here are decompositions:

11 + 31523027 = 31523038
17 + 31523021 = 31523038
59 + 31522979 = 31523038
101 + 31522937 = 31523038
137 + 31522901 = 31523038
149 + 31522889 = 31523038
191 + 31522847 = 31523038
509 + 31522529 = 31523038

Showing the first eight; more decompositions exist.
