Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526286, here are decompositions:

3 + 526283 = 526286
37 + 526249 = 526286
73 + 526213 = 526286
97 + 526189 = 526286
127 + 526159 = 526286
199 + 526087 = 526286
223 + 526063 = 526286
307 + 525979 = 526286

Showing the first eight; more decompositions exist.
