Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573756, here are decompositions:

3 + 31573753 = 31573756
59 + 31573697 = 31573756
113 + 31573643 = 31573756
173 + 31573583 = 31573756
197 + 31573559 = 31573756
233 + 31573523 = 31573756
257 + 31573499 = 31573756
293 + 31573463 = 31573756

Showing the first eight; more decompositions exist.
