Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503234, here are decompositions:

5 + 31503229 = 31503234
17 + 31503217 = 31503234
31 + 31503203 = 31503234
53 + 31503181 = 31503234
67 + 31503167 = 31503234
83 + 31503151 = 31503234
127 + 31503107 = 31503234
131 + 31503103 = 31503234

Showing the first eight; more decompositions exist.
