Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 514820, here are decompositions:

37 + 514783 = 514820
73 + 514747 = 514820
79 + 514741 = 514820
109 + 514711 = 514820
139 + 514681 = 514820
151 + 514669 = 514820
181 + 514639 = 514820
199 + 514621 = 514820

Showing the first eight; more decompositions exist.
