Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493820, here are decompositions:

3 + 493817 = 493820
7 + 493813 = 493820
13 + 493807 = 493820
43 + 493777 = 493820
73 + 493747 = 493820
109 + 493711 = 493820
127 + 493693 = 493820
163 + 493657 = 493820

Showing the first eight; more decompositions exist.
