Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25170, here are decompositions:

7 + 25163 = 25170
17 + 25153 = 25170
23 + 25147 = 25170
43 + 25127 = 25170
53 + 25117 = 25170
59 + 25111 = 25170
73 + 25097 = 25170
83 + 25087 = 25170

Showing the first eight; more decompositions exist.
