Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523978, here are decompositions:

29 + 523949 = 523978
41 + 523937 = 523978
71 + 523907 = 523978
101 + 523877 = 523978
131 + 523847 = 523978
149 + 523829 = 523978
311 + 523667 = 523978
347 + 523631 = 523978

Showing the first eight; more decompositions exist.
