Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468068, here are decompositions:

41 + 31468027 = 31468068
67 + 31468001 = 31468068
101 + 31467967 = 31468068
131 + 31467937 = 31468068
157 + 31467911 = 31468068
239 + 31467829 = 31468068
257 + 31467811 = 31468068
347 + 31467721 = 31468068

Showing the first eight; more decompositions exist.
