Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43642, here are decompositions:
- 29 + 43613 = 43642
- 101 + 43541 = 43642
- 191 + 43451 = 43642
- 239 + 43403 = 43642
- 251 + 43391 = 43642
- 311 + 43331 = 43642
- 359 + 43283 = 43642
- 419 + 43223 = 43642
Showing the first eight; more decompositions exist.
