Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460196, here are decompositions:

23 + 31460173 = 31460196
29 + 31460167 = 31460196
59 + 31460137 = 31460196
67 + 31460129 = 31460196
179 + 31460017 = 31460196
197 + 31459999 = 31460196
233 + 31459963 = 31460196
337 + 31459859 = 31460196

Showing the first eight; more decompositions exist.
