Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523068, here are decompositions:

41 + 31523027 = 31523068
47 + 31523021 = 31523068
89 + 31522979 = 31523068
107 + 31522961 = 31523068
131 + 31522937 = 31523068
167 + 31522901 = 31523068
179 + 31522889 = 31523068
617 + 31522451 = 31523068

Showing the first eight; more decompositions exist.
