Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573384, here are decompositions:

23 + 31573361 = 31573384
107 + 31573277 = 31573384
131 + 31573253 = 31573384
173 + 31573211 = 31573384
233 + 31573151 = 31573384
251 + 31573133 = 31573384
257 + 31573127 = 31573384
281 + 31573103 = 31573384

Showing the first eight; more decompositions exist.
