Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607552, here are decompositions:

79 + 31607473 = 31607552
103 + 31607449 = 31607552
211 + 31607341 = 31607552
271 + 31607281 = 31607552
601 + 31606951 = 31607552
673 + 31606879 = 31607552
811 + 31606741 = 31607552
1009 + 31606543 = 31607552

Showing the first eight; more decompositions exist.
