Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531122, here are decompositions:

19 + 531103 = 531122
43 + 531079 = 531122
79 + 531043 = 531122
139 + 530983 = 531122
211 + 530911 = 531122
271 + 530851 = 531122
349 + 530773 = 531122
379 + 530743 = 531122

Showing the first eight; more decompositions exist.
