Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523738, here are decompositions:

71 + 523667 = 523738
101 + 523637 = 523738
107 + 523631 = 523738
167 + 523571 = 523738
197 + 523541 = 523738
227 + 523511 = 523738
251 + 523487 = 523738
311 + 523427 = 523738

Showing the first eight; more decompositions exist.
