Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493196, here are decompositions:

5 + 31493191 = 31493196
43 + 31493153 = 31493196
113 + 31493083 = 31493196
127 + 31493069 = 31493196
139 + 31493057 = 31493196
149 + 31493047 = 31493196
157 + 31493039 = 31493196
167 + 31493029 = 31493196

Showing the first eight; more decompositions exist.
