Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531042, here are decompositions:

19 + 531023 = 531042
53 + 530989 = 531042
59 + 530983 = 531042
73 + 530969 = 531042
131 + 530911 = 531042
173 + 530869 = 531042
181 + 530861 = 531042
191 + 530851 = 531042

Showing the first eight; more decompositions exist.
