Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530988, here are decompositions:

5 + 530983 = 530988
11 + 530977 = 530988
19 + 530969 = 530988
41 + 530947 = 530988
127 + 530861 = 530988
131 + 530857 = 530988
137 + 530851 = 530988
151 + 530837 = 530988

Showing the first eight; more decompositions exist.
