Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980686, here are decompositions:

107 + 980579 = 980686
137 + 980549 = 980686
197 + 980489 = 980686
227 + 980459 = 980686
263 + 980423 = 980686
269 + 980417 = 980686
293 + 980393 = 980686
359 + 980327 = 980686

Showing the first eight; more decompositions exist.
