Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531162, here are decompositions:

19 + 531143 = 531162
29 + 531133 = 531162
41 + 531121 = 531162
59 + 531103 = 531162
61 + 531101 = 531162
83 + 531079 = 531162
139 + 531023 = 531162
173 + 530989 = 531162

Showing the first eight; more decompositions exist.
