Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18616, here are decompositions:
- 23 + 18593 = 18616
- 29 + 18587 = 18616
- 113 + 18503 = 18616
- 173 + 18443 = 18616
- 263 + 18353 = 18616
- 347 + 18269 = 18616
- 359 + 18257 = 18616
- 383 + 18233 = 18616
Showing the first eight; more decompositions exist.
