Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523564, here are decompositions:

11 + 523553 = 523564
23 + 523541 = 523564
53 + 523511 = 523564
71 + 523493 = 523564
101 + 523463 = 523564
131 + 523433 = 523564
137 + 523427 = 523564
257 + 523307 = 523564

Showing the first eight; more decompositions exist.
