Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13786, here are decompositions:
- 5 + 13781 = 13786
- 23 + 13763 = 13786
- 29 + 13757 = 13786
- 89 + 13697 = 13786
- 107 + 13679 = 13786
- 137 + 13649 = 13786
- 167 + 13619 = 13786
- 173 + 13613 = 13786
Showing the first eight; more decompositions exist.
