Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529240, here are decompositions:

3 + 529237 = 529240
11 + 529229 = 529240
59 + 529181 = 529240
83 + 529157 = 529240
113 + 529127 = 529240
137 + 529103 = 529240
191 + 529049 = 529240
197 + 529043 = 529240

Showing the first eight; more decompositions exist.
