Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494402, here are decompositions:

19 + 494383 = 494402
43 + 494359 = 494402
61 + 494341 = 494402
151 + 494251 = 494402
211 + 494191 = 494402
373 + 494029 = 494402
379 + 494023 = 494402
409 + 493993 = 494402

Showing the first eight; more decompositions exist.
