Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30248, here are decompositions:
- 7 + 30241 = 30248
- 37 + 30211 = 30248
- 61 + 30187 = 30248
- 67 + 30181 = 30248
- 79 + 30169 = 30248
- 109 + 30139 = 30248
- 139 + 30109 = 30248
- 151 + 30097 = 30248
Showing the first eight; more decompositions exist.
