Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573232, here are decompositions:

43 + 31573189 = 31573232
79 + 31573153 = 31573232
109 + 31573123 = 31573232
139 + 31573093 = 31573232
211 + 31573021 = 31573232
283 + 31572949 = 31573232
331 + 31572901 = 31573232
409 + 31572823 = 31573232

Showing the first eight; more decompositions exist.
