Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446482, here are decompositions:

43 + 31446439 = 31446482
229 + 31446253 = 31446482
241 + 31446241 = 31446482
271 + 31446211 = 31446482
349 + 31446133 = 31446482
421 + 31446061 = 31446482
499 + 31445983 = 31446482
523 + 31445959 = 31446482

Showing the first eight; more decompositions exist.
