Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28844, here are decompositions:

7 + 28837 = 28844
31 + 28813 = 28844
37 + 28807 = 28844
73 + 28771 = 28844
157 + 28687 = 28844
181 + 28663 = 28844
223 + 28621 = 28844
241 + 28603 = 28844

Showing the first eight; more decompositions exist.
