Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40420, here are decompositions:
- 59 + 40361 = 40420
- 131 + 40289 = 40420
- 137 + 40283 = 40420
- 167 + 40253 = 40420
- 179 + 40241 = 40420
- 227 + 40193 = 40420
- 251 + 40169 = 40420
- 257 + 40163 = 40420
Showing the first eight; more decompositions exist.
