Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468146, here are decompositions:

79 + 31468067 = 31468146
163 + 31467983 = 31468146
179 + 31467967 = 31468146
197 + 31467949 = 31468146
293 + 31467853 = 31468146
317 + 31467829 = 31468146
337 + 31467809 = 31468146
379 + 31467767 = 31468146

Showing the first eight; more decompositions exist.
