Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454644, here are decompositions:

17 + 31454627 = 31454644
131 + 31454513 = 31454644
293 + 31454351 = 31454644
443 + 31454201 = 31454644
521 + 31454123 = 31454644
563 + 31454081 = 31454644
647 + 31453997 = 31454644
653 + 31453991 = 31454644

Showing the first eight; more decompositions exist.
