Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446410, here are decompositions:

43 + 31446367 = 31446410
157 + 31446253 = 31446410
181 + 31446229 = 31446410
199 + 31446211 = 31446410
277 + 31446133 = 31446410
313 + 31446097 = 31446410
349 + 31446061 = 31446410
379 + 31446031 = 31446410

Showing the first eight; more decompositions exist.
