Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492094, here are decompositions:

3 + 31492091 = 31492094
13 + 31492081 = 31492094
43 + 31492051 = 31492094
61 + 31492033 = 31492094
181 + 31491913 = 31492094
307 + 31491787 = 31492094
367 + 31491727 = 31492094
397 + 31491697 = 31492094

Showing the first eight; more decompositions exist.
