Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526278, here are decompositions:

7 + 526271 = 526278
29 + 526249 = 526278
47 + 526231 = 526278
79 + 526199 = 526278
89 + 526189 = 526278
139 + 526139 = 526278
157 + 526121 = 526278
191 + 526087 = 526278

Showing the first eight; more decompositions exist.
