Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573026, here are decompositions:

5 + 31573021 = 31573026
19 + 31573007 = 31573026
47 + 31572979 = 31573026
83 + 31572943 = 31573026
157 + 31572869 = 31573026
257 + 31572769 = 31573026
263 + 31572763 = 31573026
293 + 31572733 = 31573026

Showing the first eight; more decompositions exist.
