Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526538, here are decompositions:

7 + 526531 = 526538
37 + 526501 = 526538
79 + 526459 = 526538
97 + 526441 = 526538
109 + 526429 = 526538
151 + 526387 = 526538
157 + 526381 = 526538
241 + 526297 = 526538

Showing the first eight; more decompositions exist.
