Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525178, here are decompositions:

11 + 525167 = 525178
41 + 525137 = 525178
149 + 525029 = 525178
179 + 524999 = 525178
197 + 524981 = 525178
239 + 524939 = 525178
257 + 524921 = 525178
347 + 524831 = 525178

Showing the first eight; more decompositions exist.
