Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526618, here are decompositions:

17 + 526601 = 526618
47 + 526571 = 526618
107 + 526511 = 526618
227 + 526391 = 526618
251 + 526367 = 526618
311 + 526307 = 526618
347 + 526271 = 526618
419 + 526199 = 526618

Showing the first eight; more decompositions exist.
