Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28608, here are decompositions:
- 5 + 28603 = 28608
- 11 + 28597 = 28608
- 17 + 28591 = 28608
- 29 + 28579 = 28608
- 37 + 28571 = 28608
- 59 + 28549 = 28608
- 61 + 28547 = 28608
- 67 + 28541 = 28608
Showing the first eight; more decompositions exist.
