Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993420, here are decompositions:

13 + 993407 = 993420
19 + 993401 = 993420
23 + 993397 = 993420
53 + 993367 = 993420
79 + 993341 = 993420
97 + 993323 = 993420
101 + 993319 = 993420
137 + 993283 = 993420

Showing the first eight; more decompositions exist.
