Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573296, here are decompositions:

17 + 31573279 = 31573296
19 + 31573277 = 31573296
37 + 31573259 = 31573296
43 + 31573253 = 31573296
107 + 31573189 = 31573296
163 + 31573133 = 31573296
173 + 31573123 = 31573296
193 + 31573103 = 31573296

Showing the first eight; more decompositions exist.
