Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531476, here are decompositions:

19 + 531457 = 531476
139 + 531337 = 531476
223 + 531253 = 531476
307 + 531169 = 531476
313 + 531163 = 531476
373 + 531103 = 531476
397 + 531079 = 531476
433 + 531043 = 531476

Showing the first eight; more decompositions exist.
