Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105722, here are decompositions:
- 31 + 105691 = 105722
- 73 + 105649 = 105722
- 103 + 105619 = 105722
- 109 + 105613 = 105722
- 181 + 105541 = 105722
- 193 + 105529 = 105722
- 223 + 105499 = 105722
- 349 + 105373 = 105722
Showing the first eight; more decompositions exist.
