Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525250, here are decompositions:

3 + 525247 = 525250
29 + 525221 = 525250
41 + 525209 = 525250
59 + 525191 = 525250
83 + 525167 = 525250
107 + 525143 = 525250
113 + 525137 = 525250
149 + 525101 = 525250

Showing the first eight; more decompositions exist.
