Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527388, here are decompositions:

7 + 527381 = 527388
11 + 527377 = 527388
41 + 527347 = 527388
61 + 527327 = 527388
97 + 527291 = 527388
107 + 527281 = 527388
137 + 527251 = 527388
151 + 527237 = 527388

Showing the first eight; more decompositions exist.
