Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62440, here are decompositions:
- 17 + 62423 = 62440
- 23 + 62417 = 62440
- 89 + 62351 = 62440
- 113 + 62327 = 62440
- 137 + 62303 = 62440
- 167 + 62273 = 62440
- 227 + 62213 = 62440
- 233 + 62207 = 62440
Showing the first eight; more decompositions exist.
