Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525004, here are decompositions:

3 + 525001 = 525004
5 + 524999 = 525004
23 + 524981 = 525004
41 + 524963 = 525004
47 + 524957 = 525004
71 + 524933 = 525004
83 + 524921 = 525004
131 + 524873 = 525004

Showing the first eight; more decompositions exist.
