Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41390, here are decompositions:
- 3 + 41387 = 41390
- 109 + 41281 = 41390
- 127 + 41263 = 41390
- 157 + 41233 = 41390
- 163 + 41227 = 41390
- 211 + 41179 = 41390
- 229 + 41161 = 41390
- 241 + 41149 = 41390
Showing the first eight; more decompositions exist.
