Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40448, here are decompositions:
- 19 + 40429 = 40448
- 61 + 40387 = 40448
- 97 + 40351 = 40448
- 211 + 40237 = 40448
- 271 + 40177 = 40448
- 337 + 40111 = 40448
- 349 + 40099 = 40448
- 409 + 40039 = 40448
Showing the first eight; more decompositions exist.
