Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523572, here are decompositions:

19 + 523553 = 523572
29 + 523543 = 523572
31 + 523541 = 523572
53 + 523519 = 523572
61 + 523511 = 523572
79 + 523493 = 523572
83 + 523489 = 523572
109 + 523463 = 523572

Showing the first eight; more decompositions exist.
