Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574252, here are decompositions:

19 + 31574233 = 31574252
79 + 31574173 = 31574252
181 + 31574071 = 31574252
211 + 31574041 = 31574252
421 + 31573831 = 31574252
433 + 31573819 = 31574252
499 + 31573753 = 31574252
613 + 31573639 = 31574252

Showing the first eight; more decompositions exist.
