Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25206, here are decompositions:

17 + 25189 = 25206
23 + 25183 = 25206
37 + 25169 = 25206
43 + 25163 = 25206
53 + 25153 = 25206
59 + 25147 = 25206
79 + 25127 = 25206
89 + 25117 = 25206

Showing the first eight; more decompositions exist.
