Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573314, here are decompositions:

37 + 31573277 = 31573314
53 + 31573261 = 31573314
61 + 31573253 = 31573314
103 + 31573211 = 31573314
151 + 31573163 = 31573314
163 + 31573151 = 31573314
181 + 31573133 = 31573314
191 + 31573123 = 31573314

Showing the first eight; more decompositions exist.
