Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567176, here are decompositions:

19 + 31567157 = 31567176
23 + 31567153 = 31567176
89 + 31567087 = 31567176
127 + 31567049 = 31567176
197 + 31566979 = 31567176
257 + 31566919 = 31567176
313 + 31566863 = 31567176
337 + 31566839 = 31567176

Showing the first eight; more decompositions exist.
