Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29642, here are decompositions:
- 13 + 29629 = 29642
- 31 + 29611 = 29642
- 43 + 29599 = 29642
- 61 + 29581 = 29642
- 73 + 29569 = 29642
- 199 + 29443 = 29642
- 241 + 29401 = 29642
- 331 + 29311 = 29642
Showing the first eight; more decompositions exist.
