Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526220, here are decompositions:

7 + 526213 = 526220
31 + 526189 = 526220
61 + 526159 = 526220
103 + 526117 = 526220
151 + 526069 = 526220
157 + 526063 = 526220
193 + 526027 = 526220
241 + 525979 = 526220

Showing the first eight; more decompositions exist.
