Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531084, here are decompositions:

5 + 531079 = 531084
13 + 531071 = 531084
41 + 531043 = 531084
61 + 531023 = 531084
67 + 531017 = 531084
101 + 530983 = 531084
107 + 530977 = 531084
137 + 530947 = 531084

Showing the first eight; more decompositions exist.
