Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574328, here are decompositions:

31 + 31574297 = 31574328
67 + 31574261 = 31574328
127 + 31574201 = 31574328
197 + 31574131 = 31574328
229 + 31574099 = 31574328
257 + 31574071 = 31574328
281 + 31574047 = 31574328
307 + 31574021 = 31574328

Showing the first eight; more decompositions exist.
