Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29278, here are decompositions:
- 47 + 29231 = 29278
- 71 + 29207 = 29278
- 131 + 29147 = 29278
- 149 + 29129 = 29278
- 251 + 29027 = 29278
- 257 + 29021 = 29278
- 269 + 29009 = 29278
- 317 + 28961 = 29278
Showing the first eight; more decompositions exist.
