Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523112, here are decompositions:

13 + 31523099 = 31523112
31 + 31523081 = 31523112
59 + 31523053 = 31523112
109 + 31523003 = 31523112
151 + 31522961 = 31523112
211 + 31522901 = 31523112
223 + 31522889 = 31523112
239 + 31522873 = 31523112

Showing the first eight; more decompositions exist.
