Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492806, here are decompositions:

5 + 31492801 = 31492806
29 + 31492777 = 31492806
109 + 31492697 = 31492806
139 + 31492667 = 31492806
179 + 31492627 = 31492806
229 + 31492577 = 31492806
239 + 31492567 = 31492806
269 + 31492537 = 31492806

Showing the first eight; more decompositions exist.
