Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526988, here are decompositions:

31 + 526957 = 526988
37 + 526951 = 526988
79 + 526909 = 526988
151 + 526837 = 526988
157 + 526831 = 526988
211 + 526777 = 526988
229 + 526759 = 526988
271 + 526717 = 526988

Showing the first eight; more decompositions exist.
