Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2226, here are decompositions:
- 5 + 2221 = 2226
- 13 + 2213 = 2226
- 19 + 2207 = 2226
- 23 + 2203 = 2226
- 47 + 2179 = 2226
- 73 + 2153 = 2226
- 83 + 2143 = 2226
- 89 + 2137 = 2226
Showing the first eight; more decompositions exist.
