Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30188, here are decompositions:
- 7 + 30181 = 30188
- 19 + 30169 = 30188
- 79 + 30109 = 30188
- 97 + 30091 = 30188
- 199 + 29989 = 30188
- 229 + 29959 = 30188
- 241 + 29947 = 30188
- 271 + 29917 = 30188
Showing the first eight; more decompositions exist.
