Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574222, here are decompositions:

19 + 31574203 = 31574222
151 + 31574071 = 31574222
181 + 31574041 = 31574222
223 + 31573999 = 31574222
601 + 31573621 = 31574222
661 + 31573561 = 31574222
709 + 31573513 = 31574222
829 + 31573393 = 31574222

Showing the first eight; more decompositions exist.
