Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493872, here are decompositions:

13 + 493859 = 493872
19 + 493853 = 493872
59 + 493813 = 493872
61 + 493811 = 493872
79 + 493793 = 493872
139 + 493733 = 493872
151 + 493721 = 493872
163 + 493709 = 493872

Showing the first eight; more decompositions exist.
