Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573284, here are decompositions:

5 + 31573279 = 31573284
7 + 31573277 = 31573284
23 + 31573261 = 31573284
31 + 31573253 = 31573284
73 + 31573211 = 31573284
131 + 31573153 = 31573284
151 + 31573133 = 31573284
157 + 31573127 = 31573284

Showing the first eight; more decompositions exist.
