Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40618, here are decompositions:
- 41 + 40577 = 40618
- 59 + 40559 = 40618
- 89 + 40529 = 40618
- 131 + 40487 = 40618
- 191 + 40427 = 40618
- 257 + 40361 = 40618
- 449 + 40169 = 40618
- 467 + 40151 = 40618
Showing the first eight; more decompositions exist.
