Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525136, here are decompositions:

107 + 525029 = 525136
137 + 524999 = 525136
167 + 524969 = 525136
173 + 524963 = 525136
179 + 524957 = 525136
197 + 524939 = 525136
263 + 524873 = 525136
347 + 524789 = 525136

Showing the first eight; more decompositions exist.
