Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523770, here are decompositions:

7 + 523763 = 523770
11 + 523759 = 523770
29 + 523741 = 523770
41 + 523729 = 523770
53 + 523717 = 523770
89 + 523681 = 523770
97 + 523673 = 523770
101 + 523669 = 523770

Showing the first eight; more decompositions exist.
