Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523280, here are decompositions:

19 + 523261 = 523280
61 + 523219 = 523280
67 + 523213 = 523280
73 + 523207 = 523280
103 + 523177 = 523280
151 + 523129 = 523280
337 + 522943 = 523280
397 + 522883 = 523280

Showing the first eight; more decompositions exist.
