Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573402, here are decompositions:

11 + 31573391 = 31573402
41 + 31573361 = 31573402
149 + 31573253 = 31573402
191 + 31573211 = 31573402
239 + 31573163 = 31573402
251 + 31573151 = 31573402
269 + 31573133 = 31573402
293 + 31573109 = 31573402

Showing the first eight; more decompositions exist.
