Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492114, here are decompositions:

23 + 31492091 = 31492114
41 + 31492073 = 31492114
47 + 31492067 = 31492114
53 + 31492061 = 31492114
83 + 31492031 = 31492114
131 + 31491983 = 31492114
197 + 31491917 = 31492114
233 + 31491881 = 31492114

Showing the first eight; more decompositions exist.
