Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525278, here are decompositions:

31 + 525247 = 525278
37 + 525241 = 525278
79 + 525199 = 525278
151 + 525127 = 525278
277 + 525001 = 525278
307 + 524971 = 525278
331 + 524947 = 525278
337 + 524941 = 525278

Showing the first eight; more decompositions exist.
