Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17278, here are decompositions:
- 47 + 17231 = 17278
- 71 + 17207 = 17278
- 89 + 17189 = 17278
- 179 + 17099 = 17278
- 251 + 17027 = 17278
- 257 + 17021 = 17278
- 347 + 16931 = 17278
- 389 + 16889 = 17278
Showing the first eight; more decompositions exist.
