Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526530, here are decompositions:

19 + 526511 = 526530
29 + 526501 = 526530
31 + 526499 = 526530
47 + 526483 = 526530
71 + 526459 = 526530
89 + 526441 = 526530
101 + 526429 = 526530
107 + 526423 = 526530

Showing the first eight; more decompositions exist.
