Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492066, here are decompositions:

5 + 31492061 = 31492066
83 + 31491983 = 31492066
107 + 31491959 = 31492066
149 + 31491917 = 31492066
173 + 31491893 = 31492066
317 + 31491749 = 31492066
479 + 31491587 = 31492066
503 + 31491563 = 31492066

Showing the first eight; more decompositions exist.
