Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40380, here are decompositions:
- 19 + 40361 = 40380
- 23 + 40357 = 40380
- 29 + 40351 = 40380
- 37 + 40343 = 40380
- 97 + 40283 = 40380
- 103 + 40277 = 40380
- 127 + 40253 = 40380
- 139 + 40241 = 40380
Showing the first eight; more decompositions exist.
