Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476172, here are decompositions:

3 + 31476169 = 31476172
23 + 31476149 = 31476172
29 + 31476143 = 31476172
53 + 31476119 = 31476172
59 + 31476113 = 31476172
113 + 31476059 = 31476172
263 + 31475909 = 31476172
359 + 31475813 = 31476172

Showing the first eight; more decompositions exist.
