Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79128, here are decompositions:
- 17 + 79111 = 79128
- 41 + 79087 = 79128
- 89 + 79039 = 79128
- 97 + 79031 = 79128
- 139 + 78989 = 79128
- 149 + 78979 = 79128
- 151 + 78977 = 79128
- 199 + 78929 = 79128
Showing the first eight; more decompositions exist.
