Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2270, here are decompositions:
- 3 + 2267 = 2270
- 19 + 2251 = 2270
- 31 + 2239 = 2270
- 67 + 2203 = 2270
- 109 + 2161 = 2270
- 127 + 2143 = 2270
- 139 + 2131 = 2270
- 157 + 2113 = 2270
Showing the first eight; more decompositions exist.
