Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523566, here are decompositions:

13 + 523553 = 523566
23 + 523543 = 523566
47 + 523519 = 523566
73 + 523493 = 523566
79 + 523487 = 523566
103 + 523463 = 523566
107 + 523459 = 523566
139 + 523427 = 523566

Showing the first eight; more decompositions exist.
