Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573270, here are decompositions:

11 + 31573259 = 31573270
17 + 31573253 = 31573270
59 + 31573211 = 31573270
107 + 31573163 = 31573270
137 + 31573133 = 31573270
167 + 31573103 = 31573270
233 + 31573037 = 31573270
263 + 31573007 = 31573270

Showing the first eight; more decompositions exist.
