Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567146, here are decompositions:

59 + 31567087 = 31567146
97 + 31567049 = 31567146
103 + 31567043 = 31567146
167 + 31566979 = 31567146
173 + 31566973 = 31567146
179 + 31566967 = 31567146
227 + 31566919 = 31567146
283 + 31566863 = 31567146

Showing the first eight; more decompositions exist.
