Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530998, here are decompositions:

29 + 530969 = 530998
101 + 530897 = 530998
137 + 530861 = 530998
191 + 530807 = 530998
257 + 530741 = 530998
389 + 530609 = 530998
401 + 530597 = 530998
431 + 530567 = 530998

Showing the first eight; more decompositions exist.
