Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573084, here are decompositions:

47 + 31573037 = 31573084
113 + 31572971 = 31573084
353 + 31572731 = 31573084
443 + 31572641 = 31573084
563 + 31572521 = 31573084
743 + 31572341 = 31573084
761 + 31572323 = 31573084
821 + 31572263 = 31573084

Showing the first eight; more decompositions exist.
