Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531236, here are decompositions:

7 + 531229 = 531236
67 + 531169 = 531236
73 + 531163 = 531236
103 + 531133 = 531236
157 + 531079 = 531236
193 + 531043 = 531236
367 + 530869 = 531236
379 + 530857 = 531236

Showing the first eight; more decompositions exist.
