Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476310, here are decompositions:

59 + 31476251 = 31476310
71 + 31476239 = 31476310
167 + 31476143 = 31476310
191 + 31476119 = 31476310
197 + 31476113 = 31476310
251 + 31476059 = 31476310
293 + 31476017 = 31476310
347 + 31475963 = 31476310

Showing the first eight; more decompositions exist.
