Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43390, here are decompositions:
- 59 + 43331 = 43390
- 71 + 43319 = 43390
- 107 + 43283 = 43390
- 167 + 43223 = 43390
- 239 + 43151 = 43390
- 257 + 43133 = 43390
- 353 + 43037 = 43390
- 401 + 42989 = 43390
Showing the first eight; more decompositions exist.
