Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27228, here are decompositions:
- 17 + 27211 = 27228
- 31 + 27197 = 27228
- 37 + 27191 = 27228
- 101 + 27127 = 27228
- 137 + 27091 = 27228
- 151 + 27077 = 27228
- 167 + 27061 = 27228
- 197 + 27031 = 27228
Showing the first eight; more decompositions exist.
