Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40386, here are decompositions:
- 29 + 40357 = 40386
- 43 + 40343 = 40386
- 97 + 40289 = 40386
- 103 + 40283 = 40386
- 109 + 40277 = 40386
- 149 + 40237 = 40386
- 173 + 40213 = 40386
- 193 + 40193 = 40386
Showing the first eight; more decompositions exist.
