Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576108, here are decompositions:

17 + 31576091 = 31576108
41 + 31576067 = 31576108
59 + 31576049 = 31576108
71 + 31576037 = 31576108
101 + 31576007 = 31576108
107 + 31576001 = 31576108
191 + 31575917 = 31576108
227 + 31575881 = 31576108

Showing the first eight; more decompositions exist.
