Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446266, here are decompositions:

13 + 31446253 = 31446266
37 + 31446229 = 31446266
43 + 31446223 = 31446266
199 + 31446067 = 31446266
283 + 31445983 = 31446266
307 + 31445959 = 31446266
337 + 31445929 = 31446266
349 + 31445917 = 31446266

Showing the first eight; more decompositions exist.
