Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523722, here are decompositions:

5 + 523717 = 523722
41 + 523681 = 523722
53 + 523669 = 523722
83 + 523639 = 523722
149 + 523573 = 523722
151 + 523571 = 523722
179 + 523543 = 523722
181 + 523541 = 523722

Showing the first eight; more decompositions exist.
