Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523518, here are decompositions:

7 + 523511 = 523518
29 + 523489 = 523518
31 + 523487 = 523518
59 + 523459 = 523518
101 + 523417 = 523518
131 + 523387 = 523518
167 + 523351 = 523518
211 + 523307 = 523518

Showing the first eight; more decompositions exist.
