Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525516, here are decompositions:

23 + 525493 = 525516
59 + 525457 = 525516
83 + 525433 = 525516
107 + 525409 = 525516
137 + 525379 = 525516
139 + 525377 = 525516
157 + 525359 = 525516
163 + 525353 = 525516

Showing the first eight; more decompositions exist.
