Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523560, here are decompositions:

7 + 523553 = 523560
17 + 523543 = 523560
19 + 523541 = 523560
41 + 523519 = 523560
67 + 523493 = 523560
71 + 523489 = 523560
73 + 523487 = 523560
97 + 523463 = 523560

Showing the first eight; more decompositions exist.
