Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476256, here are decompositions:

5 + 31476251 = 31476256
17 + 31476239 = 31476256
107 + 31476149 = 31476256
113 + 31476143 = 31476256
137 + 31476119 = 31476256
197 + 31476059 = 31476256
239 + 31476017 = 31476256
293 + 31475963 = 31476256

Showing the first eight; more decompositions exist.
