Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463236, here are decompositions:

23 + 31463213 = 31463236
89 + 31463147 = 31463236
113 + 31463123 = 31463236
137 + 31463099 = 31463236
149 + 31463087 = 31463236
173 + 31463063 = 31463236
257 + 31462979 = 31463236
347 + 31462889 = 31463236

Showing the first eight; more decompositions exist.
