Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526438, here are decompositions:

41 + 526397 = 526438
47 + 526391 = 526438
71 + 526367 = 526438
131 + 526307 = 526438
149 + 526289 = 526438
167 + 526271 = 526438
239 + 526199 = 526438
281 + 526157 = 526438

Showing the first eight; more decompositions exist.
