Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523522, here are decompositions:

3 + 523519 = 523522
11 + 523511 = 523522
29 + 523493 = 523522
59 + 523463 = 523522
89 + 523433 = 523522
173 + 523349 = 523522
353 + 523169 = 523522
491 + 523031 = 523522

Showing the first eight; more decompositions exist.
