Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526658, here are decompositions:

7 + 526651 = 526658
31 + 526627 = 526658
127 + 526531 = 526658
157 + 526501 = 526658
199 + 526459 = 526658
229 + 526429 = 526658
271 + 526387 = 526658
277 + 526381 = 526658

Showing the first eight; more decompositions exist.
