Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527728, here are decompositions:

29 + 527699 = 527728
101 + 527627 = 527728
137 + 527591 = 527728
239 + 527489 = 527728
281 + 527447 = 527728
317 + 527411 = 527728
347 + 527381 = 527728
401 + 527327 = 527728

Showing the first eight; more decompositions exist.
