Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476130, here are decompositions:

11 + 31476119 = 31476130
17 + 31476113 = 31476130
71 + 31476059 = 31476130
113 + 31476017 = 31476130
167 + 31475963 = 31476130
281 + 31475849 = 31476130
317 + 31475813 = 31476130
353 + 31475777 = 31476130

Showing the first eight; more decompositions exist.
