Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574524, here are decompositions:

17 + 31574507 = 31574524
71 + 31574453 = 31574524
197 + 31574327 = 31574524
227 + 31574297 = 31574524
263 + 31574261 = 31574524
431 + 31574093 = 31574524
503 + 31574021 = 31574524
557 + 31573967 = 31574524

Showing the first eight; more decompositions exist.
