Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523890, here are decompositions:

13 + 523877 = 523890
23 + 523867 = 523890
43 + 523847 = 523890
61 + 523829 = 523890
89 + 523801 = 523890
97 + 523793 = 523890
113 + 523777 = 523890
127 + 523763 = 523890

Showing the first eight; more decompositions exist.
