Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573046, here are decompositions:

19 + 31573027 = 31573046
67 + 31572979 = 31573046
97 + 31572949 = 31573046
103 + 31572943 = 31573046
223 + 31572823 = 31573046
277 + 31572769 = 31573046
283 + 31572763 = 31573046
313 + 31572733 = 31573046

Showing the first eight; more decompositions exist.
