Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573060, here are decompositions:

3 + 31573057 = 31573060
23 + 31573037 = 31573060
53 + 31573007 = 31573060
89 + 31572971 = 31573060
179 + 31572881 = 31573060
191 + 31572869 = 31573060
251 + 31572809 = 31573060
347 + 31572713 = 31573060

Showing the first eight; more decompositions exist.
