Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525138, here are decompositions:

11 + 525127 = 525138
37 + 525101 = 525138
109 + 525029 = 525138
137 + 525001 = 525138
139 + 524999 = 525138
157 + 524981 = 525138
167 + 524971 = 525138
179 + 524959 = 525138

Showing the first eight; more decompositions exist.
