Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525450, here are decompositions:

11 + 525439 = 525450
17 + 525433 = 525450
19 + 525431 = 525450
41 + 525409 = 525450
53 + 525397 = 525450
59 + 525391 = 525450
71 + 525379 = 525450
73 + 525377 = 525450

Showing the first eight; more decompositions exist.
