Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27428, here are decompositions:
- 19 + 27409 = 27428
- 31 + 27397 = 27428
- 61 + 27367 = 27428
- 67 + 27361 = 27428
- 151 + 27277 = 27428
- 157 + 27271 = 27428
- 337 + 27091 = 27428
- 367 + 27061 = 27428
Showing the first eight; more decompositions exist.
