Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523986, here are decompositions:

17 + 523969 = 523986
37 + 523949 = 523986
59 + 523927 = 523986
79 + 523907 = 523986
83 + 523903 = 523986
109 + 523877 = 523986
139 + 523847 = 523986
157 + 523829 = 523986

Showing the first eight; more decompositions exist.
