Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567122, here are decompositions:

31 + 31567091 = 31567122
73 + 31567049 = 31567122
79 + 31567043 = 31567122
149 + 31566973 = 31567122
211 + 31566911 = 31567122
283 + 31566839 = 31567122
359 + 31566763 = 31567122
373 + 31566749 = 31567122

Showing the first eight; more decompositions exist.
