Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573162, here are decompositions:

11 + 31573151 = 31573162
29 + 31573133 = 31573162
53 + 31573109 = 31573162
59 + 31573103 = 31573162
191 + 31572971 = 31573162
281 + 31572881 = 31573162
293 + 31572869 = 31573162
353 + 31572809 = 31573162

Showing the first eight; more decompositions exist.
