Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979380, here are decompositions:

7 + 979373 = 979380
11 + 979369 = 979380
19 + 979361 = 979380
37 + 979343 = 979380
43 + 979337 = 979380
47 + 979333 = 979380
53 + 979327 = 979380
67 + 979313 = 979380

Showing the first eight; more decompositions exist.
