Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29286, here are decompositions:
- 17 + 29269 = 29286
- 43 + 29243 = 29286
- 79 + 29207 = 29286
- 107 + 29179 = 29286
- 113 + 29173 = 29286
- 139 + 29147 = 29286
- 149 + 29137 = 29286
- 157 + 29129 = 29286
Showing the first eight; more decompositions exist.
