Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492804, here are decompositions:

3 + 31492801 = 31492804
23 + 31492781 = 31492804
47 + 31492757 = 31492804
53 + 31492751 = 31492804
107 + 31492697 = 31492804
113 + 31492691 = 31492804
137 + 31492667 = 31492804
227 + 31492577 = 31492804

Showing the first eight; more decompositions exist.
