Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525100, here are decompositions:

71 + 525029 = 525100
83 + 525017 = 525100
101 + 524999 = 525100
131 + 524969 = 525100
137 + 524963 = 525100
167 + 524933 = 525100
179 + 524921 = 525100
227 + 524873 = 525100

Showing the first eight; more decompositions exist.
