Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523874, here are decompositions:

7 + 523867 = 523874
73 + 523801 = 523874
97 + 523777 = 523874
103 + 523771 = 523874
157 + 523717 = 523874
193 + 523681 = 523874
271 + 523603 = 523874
277 + 523597 = 523874

Showing the first eight; more decompositions exist.
