Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573024, here are decompositions:

3 + 31573021 = 31573024
17 + 31573007 = 31573024
53 + 31572971 = 31573024
83 + 31572941 = 31573024
293 + 31572731 = 31573024
311 + 31572713 = 31573024
383 + 31572641 = 31573024
491 + 31572533 = 31573024

Showing the first eight; more decompositions exist.
