Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503664, here are decompositions:

107 + 31503557 = 31503664
461 + 31503203 = 31503664
557 + 31503107 = 31503664
701 + 31502963 = 31503664
887 + 31502777 = 31503664
977 + 31502687 = 31503664
1103 + 31502561 = 31503664
1181 + 31502483 = 31503664

Showing the first eight; more decompositions exist.
