Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503736, here are decompositions:

3 + 31503733 = 31503736
23 + 31503713 = 31503736
167 + 31503569 = 31503736
179 + 31503557 = 31503736
227 + 31503509 = 31503736
293 + 31503443 = 31503736
557 + 31503179 = 31503736
569 + 31503167 = 31503736

Showing the first eight; more decompositions exist.
