Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525144, here are decompositions:

7 + 525137 = 525144
17 + 525127 = 525144
43 + 525101 = 525144
101 + 525043 = 525144
127 + 525017 = 525144
131 + 525013 = 525144
163 + 524981 = 525144
173 + 524971 = 525144

Showing the first eight; more decompositions exist.
