Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532228, here are decompositions:

19 + 31532209 = 31532228
61 + 31532167 = 31532228
139 + 31532089 = 31532228
157 + 31532071 = 31532228
307 + 31531921 = 31532228
601 + 31531627 = 31532228
757 + 31531471 = 31532228
811 + 31531417 = 31532228

Showing the first eight; more decompositions exist.
