Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492896, here are decompositions:

37 + 31492859 = 31492896
47 + 31492849 = 31492896
59 + 31492837 = 31492896
139 + 31492757 = 31492896
199 + 31492697 = 31492896
229 + 31492667 = 31492896
233 + 31492663 = 31492896
269 + 31492627 = 31492896

Showing the first eight; more decompositions exist.
