Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493380, here are decompositions:

11 + 493369 = 493380
29 + 493351 = 493380
47 + 493333 = 493380
67 + 493313 = 493380
79 + 493301 = 493380
89 + 493291 = 493380
101 + 493279 = 493380
103 + 493277 = 493380

Showing the first eight; more decompositions exist.
