Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81754, here are decompositions:
- 5 + 81749 = 81754
- 17 + 81737 = 81754
- 47 + 81707 = 81754
- 53 + 81701 = 81754
- 83 + 81671 = 81754
- 107 + 81647 = 81754
- 191 + 81563 = 81754
- 227 + 81527 = 81754
Showing the first eight; more decompositions exist.
