Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573416, here are decompositions:

23 + 31573393 = 31573416
53 + 31573363 = 31573416
59 + 31573357 = 31573416
137 + 31573279 = 31573416
139 + 31573277 = 31573416
157 + 31573259 = 31573416
163 + 31573253 = 31573416
227 + 31573189 = 31573416

Showing the first eight; more decompositions exist.
