Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503112, here are decompositions:

5 + 31503107 = 31503112
59 + 31503053 = 31503112
149 + 31502963 = 31503112
653 + 31502459 = 31503112
929 + 31502183 = 31503112
983 + 31502129 = 31503112
1013 + 31502099 = 31503112
1289 + 31501823 = 31503112

Showing the first eight; more decompositions exist.
