Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573066, here are decompositions:

29 + 31573037 = 31573066
59 + 31573007 = 31573066
197 + 31572869 = 31573066
257 + 31572809 = 31573066
353 + 31572713 = 31573066
419 + 31572647 = 31573066
653 + 31572413 = 31573066
677 + 31572389 = 31573066

Showing the first eight; more decompositions exist.
