Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28676, here are decompositions:
- 7 + 28669 = 28676
- 13 + 28663 = 28676
- 19 + 28657 = 28676
- 73 + 28603 = 28676
- 79 + 28597 = 28676
- 97 + 28579 = 28676
- 103 + 28573 = 28676
- 127 + 28549 = 28676
Showing the first eight; more decompositions exist.
