Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531164, here are decompositions:

31 + 531133 = 531164
43 + 531121 = 531164
61 + 531103 = 531164
181 + 530983 = 531164
307 + 530857 = 531164
313 + 530851 = 531164
331 + 530833 = 531164
367 + 530797 = 531164

Showing the first eight; more decompositions exist.
