Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513790, here are decompositions:

23 + 513767 = 513790
29 + 513761 = 513790
41 + 513749 = 513790
59 + 513731 = 513790
71 + 513719 = 513790
107 + 513683 = 513790
149 + 513641 = 513790
197 + 513593 = 513790

Showing the first eight; more decompositions exist.
