Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527128, here are decompositions:

5 + 527123 = 527128
29 + 527099 = 527128
47 + 527081 = 527128
59 + 527069 = 527128
71 + 527057 = 527128
131 + 526997 = 527128
191 + 526937 = 527128
197 + 526931 = 527128

Showing the first eight; more decompositions exist.
