Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573774, here are decompositions:

17 + 31573757 = 31573774
131 + 31573643 = 31573774
191 + 31573583 = 31573774
251 + 31573523 = 31573774
311 + 31573463 = 31573774
347 + 31573427 = 31573774
383 + 31573391 = 31573774
521 + 31573253 = 31573774

Showing the first eight; more decompositions exist.
