Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12380, here are decompositions:

3 + 12377 = 12380
7 + 12373 = 12380
37 + 12343 = 12380
79 + 12301 = 12380
103 + 12277 = 12380
127 + 12253 = 12380
139 + 12241 = 12380
223 + 12157 = 12380

Showing the first eight; more decompositions exist.
