Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123644, here are decompositions:

7 + 123637 = 123644
13 + 123631 = 123644
43 + 123601 = 123644
61 + 123583 = 123644
97 + 123547 = 123644
127 + 123517 = 123644
151 + 123493 = 123644
211 + 123433 = 123644

Showing the first eight; more decompositions exist.
