Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526542, here are decompositions:

11 + 526531 = 526542
31 + 526511 = 526542
41 + 526501 = 526542
43 + 526499 = 526542
59 + 526483 = 526542
83 + 526459 = 526542
89 + 526453 = 526542
101 + 526441 = 526542

Showing the first eight; more decompositions exist.
