Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15676, here are decompositions:
- 5 + 15671 = 15676
- 29 + 15647 = 15676
- 47 + 15629 = 15676
- 107 + 15569 = 15676
- 149 + 15527 = 15676
- 179 + 15497 = 15676
- 233 + 15443 = 15676
- 263 + 15413 = 15676
Showing the first eight; more decompositions exist.
