Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525330, here are decompositions:

17 + 525313 = 525330
31 + 525299 = 525330
73 + 525257 = 525330
83 + 525247 = 525330
89 + 525241 = 525330
109 + 525221 = 525330
131 + 525199 = 525330
137 + 525193 = 525330

Showing the first eight; more decompositions exist.
