Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576106, here are decompositions:

19 + 31576087 = 31576106
97 + 31576009 = 31576106
103 + 31576003 = 31576106
229 + 31575877 = 31576106
277 + 31575829 = 31576106
283 + 31575823 = 31576106
307 + 31575799 = 31576106
313 + 31575793 = 31576106

Showing the first eight; more decompositions exist.
