Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573062, here are decompositions:

5 + 31573057 = 31573062
41 + 31573021 = 31573062
83 + 31572979 = 31573062
113 + 31572949 = 31573062
181 + 31572881 = 31573062
193 + 31572869 = 31573062
239 + 31572823 = 31573062
293 + 31572769 = 31573062

Showing the first eight; more decompositions exist.
