Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28708, here are decompositions:
- 5 + 28703 = 28708
- 11 + 28697 = 28708
- 47 + 28661 = 28708
- 59 + 28649 = 28708
- 89 + 28619 = 28708
- 101 + 28607 = 28708
- 137 + 28571 = 28708
- 149 + 28559 = 28708
Showing the first eight; more decompositions exist.
