Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523906, here are decompositions:

3 + 523903 = 523906
29 + 523877 = 523906
59 + 523847 = 523906
113 + 523793 = 523906
233 + 523673 = 523906
239 + 523667 = 523906
269 + 523637 = 523906
353 + 523553 = 523906

Showing the first eight; more decompositions exist.
