Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525308, here are decompositions:

61 + 525247 = 525308
67 + 525241 = 525308
109 + 525199 = 525308
151 + 525157 = 525308
181 + 525127 = 525308
307 + 525001 = 525308
337 + 524971 = 525308
349 + 524959 = 525308

Showing the first eight; more decompositions exist.
