Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29918, here are decompositions:
- 37 + 29881 = 29918
- 67 + 29851 = 29918
- 157 + 29761 = 29918
- 277 + 29641 = 29918
- 307 + 29611 = 29918
- 331 + 29587 = 29918
- 337 + 29581 = 29918
- 349 + 29569 = 29918
Showing the first eight; more decompositions exist.
