Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491096, here are decompositions:

17 + 31491079 = 31491096
19 + 31491077 = 31491096
53 + 31491043 = 31491096
107 + 31490989 = 31491096
113 + 31490983 = 31491096
157 + 31490939 = 31491096
179 + 31490917 = 31491096
239 + 31490857 = 31491096

Showing the first eight; more decompositions exist.
