Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492116, here are decompositions:

23 + 31492093 = 31492116
37 + 31492079 = 31492116
43 + 31492073 = 31492116
83 + 31492033 = 31492116
127 + 31491989 = 31492116
157 + 31491959 = 31492116
199 + 31491917 = 31492116
223 + 31491893 = 31492116

Showing the first eight; more decompositions exist.
