Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40624, here are decompositions:
- 41 + 40583 = 40624
- 47 + 40577 = 40624
- 131 + 40493 = 40624
- 137 + 40487 = 40624
- 191 + 40433 = 40624
- 197 + 40427 = 40624
- 263 + 40361 = 40624
- 281 + 40343 = 40624
Showing the first eight; more decompositions exist.
