Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526390, here are decompositions:

3 + 526387 = 526390
17 + 526373 = 526390
23 + 526367 = 526390
83 + 526307 = 526390
101 + 526289 = 526390
107 + 526283 = 526390
167 + 526223 = 526390
191 + 526199 = 526390

Showing the first eight; more decompositions exist.
