Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82388, here are decompositions:
- 37 + 82351 = 82388
- 109 + 82279 = 82388
- 127 + 82261 = 82388
- 151 + 82237 = 82388
- 157 + 82231 = 82388
- 181 + 82207 = 82388
- 199 + 82189 = 82388
- 337 + 82051 = 82388
Showing the first eight; more decompositions exist.
