Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40418, here are decompositions:
- 31 + 40387 = 40418
- 61 + 40357 = 40418
- 67 + 40351 = 40418
- 181 + 40237 = 40418
- 229 + 40189 = 40418
- 241 + 40177 = 40418
- 307 + 40111 = 40418
- 331 + 40087 = 40418
Showing the first eight; more decompositions exist.
