Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105818, here are decompositions:
- 67 + 105751 = 105818
- 127 + 105691 = 105818
- 151 + 105667 = 105818
- 199 + 105619 = 105818
- 211 + 105607 = 105818
- 277 + 105541 = 105818
- 421 + 105397 = 105818
- 439 + 105379 = 105818
Showing the first eight; more decompositions exist.
