Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573202, here are decompositions:

13 + 31573189 = 31573202
79 + 31573123 = 31573202
109 + 31573093 = 31573202
181 + 31573021 = 31573202
223 + 31572979 = 31573202
379 + 31572823 = 31573202
433 + 31572769 = 31573202
439 + 31572763 = 31573202

Showing the first eight; more decompositions exist.
