Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980690, here are decompositions:

3 + 980687 = 980690
13 + 980677 = 980690
97 + 980593 = 980690
103 + 980587 = 980690
199 + 980491 = 980690
241 + 980449 = 980690
313 + 980377 = 980690
397 + 980293 = 980690

Showing the first eight; more decompositions exist.
