Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494580, here are decompositions:

13 + 494567 = 494580
17 + 494563 = 494580
19 + 494561 = 494580
41 + 494539 = 494580
59 + 494521 = 494580
61 + 494519 = 494580
83 + 494497 = 494580
109 + 494471 = 494580

Showing the first eight; more decompositions exist.
