Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492404, here are decompositions:

5 + 31492399 = 31492404
11 + 31492393 = 31492404
67 + 31492337 = 31492404
127 + 31492277 = 31492404
191 + 31492213 = 31492404
241 + 31492163 = 31492404
311 + 31492093 = 31492404
313 + 31492091 = 31492404

Showing the first eight; more decompositions exist.
