Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12500, here are decompositions:

3 + 12497 = 12500
13 + 12487 = 12500
43 + 12457 = 12500
67 + 12433 = 12500
79 + 12421 = 12500
109 + 12391 = 12500
127 + 12373 = 12500
157 + 12343 = 12500

Showing the first eight; more decompositions exist.
