Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492366, here are decompositions:

29 + 31492337 = 31492366
47 + 31492319 = 31492366
89 + 31492277 = 31492366
107 + 31492259 = 31492366
293 + 31492073 = 31492366
383 + 31491983 = 31492366
449 + 31491917 = 31492366
617 + 31491749 = 31492366

Showing the first eight; more decompositions exist.
