Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503608, here are decompositions:

79 + 31503529 = 31503608
139 + 31503469 = 31503608
229 + 31503379 = 31503608
271 + 31503337 = 31503608
277 + 31503331 = 31503608
349 + 31503259 = 31503608
379 + 31503229 = 31503608
457 + 31503151 = 31503608

Showing the first eight; more decompositions exist.
