Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523558, here are decompositions:

5 + 523553 = 523558
17 + 523541 = 523558
47 + 523511 = 523558
71 + 523487 = 523558
131 + 523427 = 523558
251 + 523307 = 523558
389 + 523169 = 523558
449 + 523109 = 523558

Showing the first eight; more decompositions exist.
