Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625222, here are decompositions:

43 + 31625179 = 31625222
73 + 31625149 = 31625222
163 + 31625059 = 31625222
271 + 31624951 = 31625222
283 + 31624939 = 31625222
373 + 31624849 = 31625222
439 + 31624783 = 31625222
523 + 31624699 = 31625222

Showing the first eight; more decompositions exist.
