Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522372, here are decompositions:

83 + 522289 = 522372
89 + 522283 = 522372
113 + 522259 = 522372
139 + 522233 = 522372
173 + 522199 = 522372
181 + 522191 = 522372
211 + 522161 = 522372
293 + 522079 = 522372

Showing the first eight; more decompositions exist.
