Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492644, here are decompositions:

3 + 492641 = 492644
13 + 492631 = 492644
43 + 492601 = 492644
157 + 492487 = 492644
181 + 492463 = 492644
223 + 492421 = 492644
241 + 492403 = 492644
541 + 492103 = 492644

Showing the first eight; more decompositions exist.
