Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530940, here are decompositions:

29 + 530911 = 530940
43 + 530897 = 530940
71 + 530869 = 530940
79 + 530861 = 530940
83 + 530857 = 530940
89 + 530851 = 530940
97 + 530843 = 530940
103 + 530837 = 530940

Showing the first eight; more decompositions exist.
