Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42634, here are decompositions:
- 23 + 42611 = 42634
- 101 + 42533 = 42634
- 167 + 42467 = 42634
- 173 + 42461 = 42634
- 191 + 42443 = 42634
- 197 + 42437 = 42634
- 227 + 42407 = 42634
- 311 + 42323 = 42634
Showing the first eight; more decompositions exist.
