Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526578, here are decompositions:

5 + 526573 = 526578
7 + 526571 = 526578
47 + 526531 = 526578
67 + 526511 = 526578
79 + 526499 = 526578
137 + 526441 = 526578
149 + 526429 = 526578
181 + 526397 = 526578

Showing the first eight; more decompositions exist.
