Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531234, here are decompositions:

5 + 531229 = 531234
31 + 531203 = 531234
37 + 531197 = 531234
61 + 531173 = 531234
71 + 531163 = 531234
101 + 531133 = 531234
113 + 531121 = 531234
131 + 531103 = 531234

Showing the first eight; more decompositions exist.
