Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493998, here are decompositions:

5 + 493993 = 493998
19 + 493979 = 493998
31 + 493967 = 493998
59 + 493939 = 493998
61 + 493937 = 493998
67 + 493931 = 493998
79 + 493919 = 493998
101 + 493897 = 493998

Showing the first eight; more decompositions exist.
