Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476460, here are decompositions:

3 + 31476457 = 31476460
11 + 31476449 = 31476460
23 + 31476437 = 31476460
47 + 31476413 = 31476460
89 + 31476371 = 31476460
107 + 31476353 = 31476460
311 + 31476149 = 31476460
317 + 31476143 = 31476460

Showing the first eight; more decompositions exist.
