Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17380, here are decompositions:
- 3 + 17377 = 17380
- 29 + 17351 = 17380
- 47 + 17333 = 17380
- 53 + 17327 = 17380
- 59 + 17321 = 17380
- 89 + 17291 = 17380
- 149 + 17231 = 17380
- 173 + 17207 = 17380
Showing the first eight; more decompositions exist.
