Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526040, here are decompositions:

3 + 526037 = 526040
13 + 526027 = 526040
61 + 525979 = 526040
79 + 525961 = 526040
103 + 525937 = 526040
127 + 525913 = 526040
223 + 525817 = 526040
271 + 525769 = 526040

Showing the first eight; more decompositions exist.
