Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531416, here are decompositions:

73 + 531343 = 531416
79 + 531337 = 531416
163 + 531253 = 531416
283 + 531133 = 531416
313 + 531103 = 531416
337 + 531079 = 531416
373 + 531043 = 531416
433 + 530983 = 531416

Showing the first eight; more decompositions exist.
