Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30008, here are decompositions:
- 19 + 29989 = 30008
- 61 + 29947 = 30008
- 127 + 29881 = 30008
- 157 + 29851 = 30008
- 337 + 29671 = 30008
- 367 + 29641 = 30008
- 379 + 29629 = 30008
- 397 + 29611 = 30008
Showing the first eight; more decompositions exist.
