Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573006, here are decompositions:

137 + 31572869 = 31573006
197 + 31572809 = 31573006
293 + 31572713 = 31573006
359 + 31572647 = 31573006
593 + 31572413 = 31573006
617 + 31572389 = 31573006
659 + 31572347 = 31573006
683 + 31572323 = 31573006

Showing the first eight; more decompositions exist.
