Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979664, here are decompositions:

13 + 979651 = 979664
97 + 979567 = 979664
193 + 979471 = 979664
241 + 979423 = 979664
331 + 979333 = 979664
337 + 979327 = 979664
373 + 979291 = 979664
457 + 979207 = 979664

Showing the first eight; more decompositions exist.
