Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525242, here are decompositions:

43 + 525199 = 525242
79 + 525163 = 525242
199 + 525043 = 525242
229 + 525013 = 525242
241 + 525001 = 525242
271 + 524971 = 525242
283 + 524959 = 525242
349 + 524893 = 525242

Showing the first eight; more decompositions exist.
