Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523790, here are decompositions:

13 + 523777 = 523790
19 + 523771 = 523790
31 + 523759 = 523790
61 + 523729 = 523790
73 + 523717 = 523790
109 + 523681 = 523790
151 + 523639 = 523790
193 + 523597 = 523790

Showing the first eight; more decompositions exist.
