Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980638, here are decompositions:

17 + 980621 = 980638
47 + 980591 = 980638
59 + 980579 = 980638
89 + 980549 = 980638
149 + 980489 = 980638
167 + 980471 = 980638
179 + 980459 = 980638
311 + 980327 = 980638

Showing the first eight; more decompositions exist.
