Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523058, here are decompositions:

5 + 31523053 = 31523058
31 + 31523027 = 31523058
37 + 31523021 = 31523058
71 + 31522987 = 31523058
79 + 31522979 = 31523058
97 + 31522961 = 31523058
107 + 31522951 = 31523058
157 + 31522901 = 31523058

Showing the first eight; more decompositions exist.
