Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30158, here are decompositions:
- 19 + 30139 = 30158
- 61 + 30097 = 30158
- 67 + 30091 = 30158
- 199 + 29959 = 30158
- 211 + 29947 = 30158
- 241 + 29917 = 30158
- 277 + 29881 = 30158
- 307 + 29851 = 30158
Showing the first eight; more decompositions exist.
