Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446626, here are decompositions:

19 + 31446607 = 31446626
73 + 31446553 = 31446626
199 + 31446427 = 31446626
373 + 31446253 = 31446626
397 + 31446229 = 31446626
643 + 31445983 = 31446626
709 + 31445917 = 31446626
907 + 31445719 = 31446626

Showing the first eight; more decompositions exist.
