Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523540, here are decompositions:

29 + 523511 = 523540
47 + 523493 = 523540
53 + 523487 = 523540
107 + 523433 = 523540
113 + 523427 = 523540
137 + 523403 = 523540
191 + 523349 = 523540
233 + 523307 = 523540

Showing the first eight; more decompositions exist.
