Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513780, here are decompositions:

11 + 513769 = 513780
13 + 513767 = 513780
19 + 513761 = 513780
31 + 513749 = 513780
41 + 513739 = 513780
53 + 513727 = 513780
61 + 513719 = 513780
83 + 513697 = 513780

Showing the first eight; more decompositions exist.
