Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573082, here are decompositions:

61 + 31573021 = 31573082
103 + 31572979 = 31573082
139 + 31572943 = 31573082
181 + 31572901 = 31573082
241 + 31572841 = 31573082
313 + 31572769 = 31573082
349 + 31572733 = 31573082
433 + 31572649 = 31573082

Showing the first eight; more decompositions exist.
