Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627404, here are decompositions:

13 + 31627391 = 31627404
31 + 31627373 = 31627404
47 + 31627357 = 31627404
71 + 31627333 = 31627404
101 + 31627303 = 31627404
157 + 31627247 = 31627404
167 + 31627237 = 31627404
271 + 31627133 = 31627404

Showing the first eight; more decompositions exist.
