Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526380, here are decompositions:

7 + 526373 = 526380
13 + 526367 = 526380
73 + 526307 = 526380
83 + 526297 = 526380
89 + 526291 = 526380
97 + 526283 = 526380
109 + 526271 = 526380
131 + 526249 = 526380

Showing the first eight; more decompositions exist.
