Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526642, here are decompositions:

5 + 526637 = 526642
23 + 526619 = 526642
41 + 526601 = 526642
59 + 526583 = 526642
71 + 526571 = 526642
131 + 526511 = 526642
251 + 526391 = 526642
269 + 526373 = 526642

Showing the first eight; more decompositions exist.
