Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29380, here are decompositions:
- 17 + 29363 = 29380
- 41 + 29339 = 29380
- 47 + 29333 = 29380
- 53 + 29327 = 29380
- 83 + 29297 = 29380
- 137 + 29243 = 29380
- 149 + 29231 = 29380
- 173 + 29207 = 29380
Showing the first eight; more decompositions exist.
