Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494304, here are decompositions:

3 + 31494301 = 31494304
11 + 31494293 = 31494304
41 + 31494263 = 31494304
47 + 31494257 = 31494304
251 + 31494053 = 31494304
263 + 31494041 = 31494304
353 + 31493951 = 31494304
521 + 31493783 = 31494304

Showing the first eight; more decompositions exist.
