Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29978, here are decompositions:
- 19 + 29959 = 29978
- 31 + 29947 = 29978
- 61 + 29917 = 29978
- 97 + 29881 = 29978
- 127 + 29851 = 29978
- 307 + 29671 = 29978
- 337 + 29641 = 29978
- 349 + 29629 = 29978
Showing the first eight; more decompositions exist.
