Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980660, here are decompositions:

19 + 980641 = 980660
61 + 980599 = 980660
67 + 980593 = 980660
73 + 980587 = 980660
103 + 980557 = 980660
157 + 980503 = 980660
211 + 980449 = 980660
229 + 980431 = 980660

Showing the first eight; more decompositions exist.
