Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980644, here are decompositions:

3 + 980641 = 980644
23 + 980621 = 980644
53 + 980591 = 980644
173 + 980471 = 980644
227 + 980417 = 980644
251 + 980393 = 980644
281 + 980363 = 980644
317 + 980327 = 980644

Showing the first eight; more decompositions exist.
