Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492198, here are decompositions:

41 + 31492157 = 31492198
107 + 31492091 = 31492198
131 + 31492067 = 31492198
137 + 31492061 = 31492198
167 + 31492031 = 31492198
239 + 31491959 = 31492198
281 + 31491917 = 31492198
317 + 31491881 = 31492198

Showing the first eight; more decompositions exist.
