Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492326, here are decompositions:

7 + 31492319 = 31492326
67 + 31492259 = 31492326
83 + 31492243 = 31492326
113 + 31492213 = 31492326
163 + 31492163 = 31492326
233 + 31492093 = 31492326
293 + 31492033 = 31492326
337 + 31491989 = 31492326

Showing the first eight; more decompositions exist.
