Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29870, here are decompositions:
- 3 + 29867 = 29870
- 7 + 29863 = 29870
- 19 + 29851 = 29870
- 37 + 29833 = 29870
- 67 + 29803 = 29870
- 109 + 29761 = 29870
- 199 + 29671 = 29870
- 229 + 29641 = 29870
Showing the first eight; more decompositions exist.
