Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525518, here are decompositions:

61 + 525457 = 525518
79 + 525439 = 525518
109 + 525409 = 525518
127 + 525391 = 525518
139 + 525379 = 525518
157 + 525361 = 525518
271 + 525247 = 525518
277 + 525241 = 525518

Showing the first eight; more decompositions exist.
