Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523830, here are decompositions:

29 + 523801 = 523830
37 + 523793 = 523830
53 + 523777 = 523830
59 + 523771 = 523830
67 + 523763 = 523830
71 + 523759 = 523830
89 + 523741 = 523830
101 + 523729 = 523830

Showing the first eight; more decompositions exist.
