Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503588, here are decompositions:

19 + 31503569 = 31503588
29 + 31503559 = 31503588
31 + 31503557 = 31503588
59 + 31503529 = 31503588
79 + 31503509 = 31503588
227 + 31503361 = 31503588
251 + 31503337 = 31503588
257 + 31503331 = 31503588

Showing the first eight; more decompositions exist.
