Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526520, here are decompositions:

19 + 526501 = 526520
37 + 526483 = 526520
61 + 526459 = 526520
67 + 526453 = 526520
79 + 526441 = 526520
97 + 526423 = 526520
139 + 526381 = 526520
223 + 526297 = 526520

Showing the first eight; more decompositions exist.
