Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72448, here are decompositions:
- 17 + 72431 = 72448
- 107 + 72341 = 72448
- 179 + 72269 = 72448
- 197 + 72251 = 72448
- 227 + 72221 = 72448
- 281 + 72167 = 72448
- 347 + 72101 = 72448
- 359 + 72089 = 72448
Showing the first eight; more decompositions exist.
