Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573132, here are decompositions:

5 + 31573127 = 31573132
23 + 31573109 = 31573132
29 + 31573103 = 31573132
191 + 31572941 = 31573132
251 + 31572881 = 31573132
263 + 31572869 = 31573132
401 + 31572731 = 31573132
419 + 31572713 = 31573132

Showing the first eight; more decompositions exist.
