Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27222, here are decompositions:
- 11 + 27211 = 27222
- 31 + 27191 = 27222
- 43 + 27179 = 27222
- 79 + 27143 = 27222
- 113 + 27109 = 27222
- 131 + 27091 = 27222
- 149 + 27073 = 27222
- 163 + 27059 = 27222
Showing the first eight; more decompositions exist.
