Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980780, here are decompositions:

7 + 980773 = 980780
61 + 980719 = 980780
103 + 980677 = 980780
139 + 980641 = 980780
181 + 980599 = 980780
193 + 980587 = 980780
223 + 980557 = 980780
277 + 980503 = 980780

Showing the first eight; more decompositions exist.
