Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567116, here are decompositions:

29 + 31567087 = 31567116
67 + 31567049 = 31567116
73 + 31567043 = 31567116
137 + 31566979 = 31567116
149 + 31566967 = 31567116
197 + 31566919 = 31567116
277 + 31566839 = 31567116
313 + 31566803 = 31567116

Showing the first eight; more decompositions exist.
