Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25182, here are decompositions:

11 + 25171 = 25182
13 + 25169 = 25182
19 + 25163 = 25182
29 + 25153 = 25182
61 + 25121 = 25182
71 + 25111 = 25182
109 + 25073 = 25182
149 + 25033 = 25182

Showing the first eight; more decompositions exist.
