Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40402, here are decompositions:
- 41 + 40361 = 40402
- 59 + 40343 = 40402
- 113 + 40289 = 40402
- 149 + 40253 = 40402
- 233 + 40169 = 40402
- 239 + 40163 = 40402
- 251 + 40151 = 40402
- 389 + 40013 = 40402
Showing the first eight; more decompositions exist.
