Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468246, here are decompositions:

3 + 31468243 = 31468246
23 + 31468223 = 31468246
149 + 31468097 = 31468246
179 + 31468067 = 31468246
233 + 31468013 = 31468246
263 + 31467983 = 31468246
347 + 31467899 = 31468246
353 + 31467893 = 31468246

Showing the first eight; more decompositions exist.
