Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526280, here are decompositions:

31 + 526249 = 526280
67 + 526213 = 526280
163 + 526117 = 526280
193 + 526087 = 526280
211 + 526069 = 526280
229 + 526051 = 526280
331 + 525949 = 526280
367 + 525913 = 526280

Showing the first eight; more decompositions exist.
