Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2288, here are decompositions:
- 7 + 2281 = 2288
- 19 + 2269 = 2288
- 37 + 2251 = 2288
- 67 + 2221 = 2288
- 109 + 2179 = 2288
- 127 + 2161 = 2288
- 151 + 2137 = 2288
- 157 + 2131 = 2288
Showing the first eight; more decompositions exist.
