Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446308, here are decompositions:

67 + 31446241 = 31446308
79 + 31446229 = 31446308
97 + 31446211 = 31446308
211 + 31446097 = 31446308
241 + 31446067 = 31446308
277 + 31446031 = 31446308
331 + 31445977 = 31446308
349 + 31445959 = 31446308

Showing the first eight; more decompositions exist.
