Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446602, here are decompositions:

163 + 31446439 = 31446602
241 + 31446361 = 31446602
349 + 31446253 = 31446602
373 + 31446229 = 31446602
379 + 31446223 = 31446602
541 + 31446061 = 31446602
571 + 31446031 = 31446602
619 + 31445983 = 31446602

Showing the first eight; more decompositions exist.
