Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40218, here are decompositions:
- 5 + 40213 = 40218
- 29 + 40189 = 40218
- 41 + 40177 = 40218
- 67 + 40151 = 40218
- 89 + 40129 = 40218
- 107 + 40111 = 40218
- 131 + 40087 = 40218
- 179 + 40039 = 40218
Showing the first eight; more decompositions exist.
