Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527240, here are decompositions:

3 + 527237 = 527240
31 + 527209 = 527240
37 + 527203 = 527240
61 + 527179 = 527240
67 + 527173 = 527240
79 + 527161 = 527240
97 + 527143 = 527240
277 + 526963 = 527240

Showing the first eight; more decompositions exist.
