Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573492, here are decompositions:

29 + 31573463 = 31573492
101 + 31573391 = 31573492
131 + 31573361 = 31573492
233 + 31573259 = 31573492
239 + 31573253 = 31573492
281 + 31573211 = 31573492
359 + 31573133 = 31573492
383 + 31573109 = 31573492

Showing the first eight; more decompositions exist.
