Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523778, here are decompositions:

7 + 523771 = 523778
19 + 523759 = 523778
37 + 523741 = 523778
61 + 523717 = 523778
97 + 523681 = 523778
109 + 523669 = 523778
139 + 523639 = 523778
181 + 523597 = 523778

Showing the first eight; more decompositions exist.
