Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526628, here are decompositions:

97 + 526531 = 526628
127 + 526501 = 526628
199 + 526429 = 526628
241 + 526387 = 526628
331 + 526297 = 526628
337 + 526291 = 526628
379 + 526249 = 526628
397 + 526231 = 526628

Showing the first eight; more decompositions exist.
