Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567194, here are decompositions:

37 + 31567157 = 31567194
41 + 31567153 = 31567194
103 + 31567091 = 31567194
107 + 31567087 = 31567194
151 + 31567043 = 31567194
227 + 31566967 = 31567194
283 + 31566911 = 31567194
293 + 31566901 = 31567194

Showing the first eight; more decompositions exist.
