Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474804, here are decompositions:

3 + 31474801 = 31474804
41 + 31474763 = 31474804
71 + 31474733 = 31474804
83 + 31474721 = 31474804
113 + 31474691 = 31474804
131 + 31474673 = 31474804
227 + 31474577 = 31474804
233 + 31474571 = 31474804

Showing the first eight; more decompositions exist.
