Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523220, here are decompositions:

7 + 523213 = 523220
13 + 523207 = 523220
43 + 523177 = 523220
127 + 523093 = 523220
199 + 523021 = 523220
277 + 522943 = 523220
337 + 522883 = 523220
349 + 522871 = 523220

Showing the first eight; more decompositions exist.
