Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607424, here are decompositions:

61 + 31607363 = 31607424
67 + 31607357 = 31607424
83 + 31607341 = 31607424
97 + 31607327 = 31607424
127 + 31607297 = 31607424
131 + 31607293 = 31607424
197 + 31607227 = 31607424
223 + 31607201 = 31607424

Showing the first eight; more decompositions exist.
