Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531244, here are decompositions:

5 + 531239 = 531244
41 + 531203 = 531244
47 + 531197 = 531244
71 + 531173 = 531244
101 + 531143 = 531244
173 + 531071 = 531244
227 + 531017 = 531244
347 + 530897 = 531244

Showing the first eight; more decompositions exist.
