Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573048, here are decompositions:

11 + 31573037 = 31573048
41 + 31573007 = 31573048
107 + 31572941 = 31573048
167 + 31572881 = 31573048
179 + 31572869 = 31573048
239 + 31572809 = 31573048
317 + 31572731 = 31573048
401 + 31572647 = 31573048

Showing the first eight; more decompositions exist.
