Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15798, here are decompositions:
- 7 + 15791 = 15798
- 11 + 15787 = 15798
- 31 + 15767 = 15798
- 37 + 15761 = 15798
- 59 + 15739 = 15798
- 61 + 15737 = 15798
- 67 + 15731 = 15798
- 71 + 15727 = 15798
Showing the first eight; more decompositions exist.
