Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493980, here are decompositions:

7 + 493973 = 493980
13 + 493967 = 493980
41 + 493939 = 493980
43 + 493937 = 493980
61 + 493919 = 493980
83 + 493897 = 493980
103 + 493877 = 493980
107 + 493873 = 493980

Showing the first eight; more decompositions exist.
