Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531204, here are decompositions:

7 + 531197 = 531204
31 + 531173 = 531204
41 + 531163 = 531204
61 + 531143 = 531204
71 + 531133 = 531204
83 + 531121 = 531204
101 + 531103 = 531204
103 + 531101 = 531204

Showing the first eight; more decompositions exist.
