Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531078, here are decompositions:

7 + 531071 = 531078
61 + 531017 = 531078
89 + 530989 = 531078
101 + 530977 = 531078
109 + 530969 = 531078
131 + 530947 = 531078
167 + 530911 = 531078
181 + 530897 = 531078

Showing the first eight; more decompositions exist.
