Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525148, here are decompositions:

5 + 525143 = 525148
11 + 525137 = 525148
47 + 525101 = 525148
131 + 525017 = 525148
149 + 524999 = 525148
167 + 524981 = 525148
179 + 524969 = 525148
191 + 524957 = 525148

Showing the first eight; more decompositions exist.
