Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12300, here are decompositions:

11 + 12289 = 12300
19 + 12281 = 12300
23 + 12277 = 12300
31 + 12269 = 12300
37 + 12263 = 12300
47 + 12253 = 12300
59 + 12241 = 12300
61 + 12239 = 12300

Showing the first eight; more decompositions exist.
