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.
