Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468090, here are decompositions:

23 + 31468067 = 31468090
89 + 31468001 = 31468090
107 + 31467983 = 31468090
179 + 31467911 = 31468090
191 + 31467899 = 31468090
197 + 31467893 = 31468090
281 + 31467809 = 31468090
443 + 31467647 = 31468090

Showing the first eight; more decompositions exist.
