Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494378, here are decompositions:

19 + 494359 = 494378
37 + 494341 = 494378
61 + 494317 = 494378
97 + 494281 = 494378
109 + 494269 = 494378
127 + 494251 = 494378
211 + 494167 = 494378
271 + 494107 = 494378

Showing the first eight; more decompositions exist.
