Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476040, here are decompositions:

23 + 31476017 = 31476040
131 + 31475909 = 31476040
191 + 31475849 = 31476040
227 + 31475813 = 31476040
263 + 31475777 = 31476040
269 + 31475771 = 31476040
359 + 31475681 = 31476040
443 + 31475597 = 31476040

Showing the first eight; more decompositions exist.
