Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27398, here are decompositions:
- 31 + 27367 = 27398
- 37 + 27361 = 27398
- 61 + 27337 = 27398
- 127 + 27271 = 27398
- 139 + 27259 = 27398
- 157 + 27241 = 27398
- 271 + 27127 = 27398
- 307 + 27091 = 27398
Showing the first eight; more decompositions exist.
