Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479304, here are decompositions:

5 + 31479299 = 31479304
53 + 31479251 = 31479304
107 + 31479197 = 31479304
173 + 31479131 = 31479304
347 + 31478957 = 31479304
821 + 31478483 = 31479304
911 + 31478393 = 31479304
953 + 31478351 = 31479304

Showing the first eight; more decompositions exist.
