Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530990, here are decompositions:

7 + 530983 = 530990
13 + 530977 = 530990
43 + 530947 = 530990
79 + 530911 = 530990
139 + 530851 = 530990
157 + 530833 = 530990
193 + 530797 = 530990
223 + 530767 = 530990

Showing the first eight; more decompositions exist.
