Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525008, here are decompositions:

7 + 525001 = 525008
37 + 524971 = 525008
61 + 524947 = 525008
67 + 524941 = 525008
109 + 524899 = 525008
139 + 524869 = 525008
151 + 524857 = 525008
181 + 524827 = 525008

Showing the first eight; more decompositions exist.
