Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468236, here are decompositions:

5 + 31468231 = 31468236
13 + 31468223 = 31468236
67 + 31468169 = 31468236
89 + 31468147 = 31468236
139 + 31468097 = 31468236
223 + 31468013 = 31468236
269 + 31467967 = 31468236
337 + 31467899 = 31468236

Showing the first eight; more decompositions exist.
