Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492248, here are decompositions:

5 + 31492243 = 31492248
157 + 31492091 = 31492248
167 + 31492081 = 31492248
181 + 31492067 = 31492248
197 + 31492051 = 31492248
331 + 31491917 = 31492248
367 + 31491881 = 31492248
457 + 31491791 = 31492248

Showing the first eight; more decompositions exist.
