Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574192, here are decompositions:

19 + 31574173 = 31574192
61 + 31574131 = 31574192
151 + 31574041 = 31574192
193 + 31573999 = 31574192
373 + 31573819 = 31574192
439 + 31573753 = 31574192
571 + 31573621 = 31574192
631 + 31573561 = 31574192

Showing the first eight; more decompositions exist.
