Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523524, here are decompositions:

5 + 523519 = 523524
13 + 523511 = 523524
31 + 523493 = 523524
37 + 523487 = 523524
61 + 523463 = 523524
97 + 523427 = 523524
107 + 523417 = 523524
137 + 523387 = 523524

Showing the first eight; more decompositions exist.
