Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23390, here are decompositions:
- 19 + 23371 = 23390
- 79 + 23311 = 23390
- 97 + 23293 = 23390
- 139 + 23251 = 23390
- 163 + 23227 = 23390
- 181 + 23209 = 23390
- 193 + 23197 = 23390
- 223 + 23167 = 23390
Showing the first eight; more decompositions exist.
