Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25212, here are decompositions:

23 + 25189 = 25212
29 + 25183 = 25212
41 + 25171 = 25212
43 + 25169 = 25212
59 + 25153 = 25212
101 + 25111 = 25212
139 + 25073 = 25212
179 + 25033 = 25212

Showing the first eight; more decompositions exist.
