Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446314, here are decompositions:

61 + 31446253 = 31446314
73 + 31446241 = 31446314
103 + 31446211 = 31446314
181 + 31446133 = 31446314
283 + 31446031 = 31446314
331 + 31445983 = 31446314
337 + 31445977 = 31446314
373 + 31445941 = 31446314

Showing the first eight; more decompositions exist.
