Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30644, here are decompositions:

7 + 30637 = 30644
13 + 30631 = 30644
67 + 30577 = 30644
127 + 30517 = 30644
151 + 30493 = 30644
241 + 30403 = 30644
277 + 30367 = 30644
331 + 30313 = 30644

Showing the first eight; more decompositions exist.
