Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40338, here are decompositions:
- 61 + 40277 = 40338
- 97 + 40241 = 40338
- 101 + 40237 = 40338
- 107 + 40231 = 40338
- 149 + 40189 = 40338
- 211 + 40127 = 40338
- 227 + 40111 = 40338
- 239 + 40099 = 40338
Showing the first eight; more decompositions exist.
