Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526518, here are decompositions:

7 + 526511 = 526518
17 + 526501 = 526518
19 + 526499 = 526518
59 + 526459 = 526518
89 + 526429 = 526518
127 + 526391 = 526518
131 + 526387 = 526518
137 + 526381 = 526518

Showing the first eight; more decompositions exist.
