Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503214, here are decompositions:

5 + 31503209 = 31503214
11 + 31503203 = 31503214
47 + 31503167 = 31503214
107 + 31503107 = 31503214
251 + 31502963 = 31503214
317 + 31502897 = 31503214
653 + 31502561 = 31503214
773 + 31502441 = 31503214

Showing the first eight; more decompositions exist.
