Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531274, here are decompositions:

11 + 531263 = 531274
71 + 531203 = 531274
101 + 531173 = 531274
131 + 531143 = 531274
173 + 531101 = 531274
251 + 531023 = 531274
257 + 531017 = 531274
431 + 530843 = 531274

Showing the first eight; more decompositions exist.
