Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527428, here are decompositions:

17 + 527411 = 527428
29 + 527399 = 527428
47 + 527381 = 527428
101 + 527327 = 527428
137 + 527291 = 527428
191 + 527237 = 527428
269 + 527159 = 527428
347 + 527081 = 527428

Showing the first eight; more decompositions exist.
