Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27380, here are decompositions:
- 13 + 27367 = 27380
- 19 + 27361 = 27380
- 43 + 27337 = 27380
- 97 + 27283 = 27380
- 103 + 27277 = 27380
- 109 + 27271 = 27380
- 127 + 27253 = 27380
- 139 + 27241 = 27380
Showing the first eight; more decompositions exist.
