Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573058, here are decompositions:

31 + 31573027 = 31573058
37 + 31573021 = 31573058
79 + 31572979 = 31573058
109 + 31572949 = 31573058
157 + 31572901 = 31573058
331 + 31572727 = 31573058
409 + 31572649 = 31573058
421 + 31572637 = 31573058

Showing the first eight; more decompositions exist.
