Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530890, here are decompositions:

29 + 530861 = 530890
47 + 530843 = 530890
53 + 530837 = 530890
83 + 530807 = 530890
137 + 530753 = 530890
149 + 530741 = 530890
179 + 530711 = 530890
197 + 530693 = 530890

Showing the first eight; more decompositions exist.
