Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493830, here are decompositions:

13 + 493817 = 493830
17 + 493813 = 493830
19 + 493811 = 493830
23 + 493807 = 493830
37 + 493793 = 493830
53 + 493777 = 493830
83 + 493747 = 493830
97 + 493733 = 493830

Showing the first eight; more decompositions exist.
