Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2238, here are decompositions:
- 17 + 2221 = 2238
- 31 + 2207 = 2238
- 59 + 2179 = 2238
- 97 + 2141 = 2238
- 101 + 2137 = 2238
- 107 + 2131 = 2238
- 109 + 2129 = 2238
- 127 + 2111 = 2238
Showing the first eight; more decompositions exist.
