Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492006, here are decompositions:

17 + 31491989 = 31492006
23 + 31491983 = 31492006
47 + 31491959 = 31492006
89 + 31491917 = 31492006
113 + 31491893 = 31492006
257 + 31491749 = 31492006
269 + 31491737 = 31492006
347 + 31491659 = 31492006

Showing the first eight; more decompositions exist.
