Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531108, here are decompositions:

5 + 531103 = 531108
7 + 531101 = 531108
29 + 531079 = 531108
37 + 531071 = 531108
131 + 530977 = 531108
139 + 530969 = 531108
197 + 530911 = 531108
211 + 530897 = 531108

Showing the first eight; more decompositions exist.
