Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40306, here are decompositions:
- 17 + 40289 = 40306
- 23 + 40283 = 40306
- 29 + 40277 = 40306
- 53 + 40253 = 40306
- 113 + 40193 = 40306
- 137 + 40169 = 40306
- 179 + 40127 = 40306
- 269 + 40037 = 40306
Showing the first eight; more decompositions exist.
