Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42644, here are decompositions:

3 + 42641 = 42644
67 + 42577 = 42644
73 + 42571 = 42644
157 + 42487 = 42644
181 + 42463 = 42644
193 + 42451 = 42644
211 + 42433 = 42644
241 + 42403 = 42644

Showing the first eight; more decompositions exist.
