Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42688, here are decompositions:
- 5 + 42683 = 42688
- 11 + 42677 = 42688
- 47 + 42641 = 42688
- 131 + 42557 = 42688
- 179 + 42509 = 42688
- 197 + 42491 = 42688
- 227 + 42461 = 42688
- 251 + 42437 = 42688
Showing the first eight; more decompositions exist.
