Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8998, here are decompositions:
- 29 + 8969 = 8998
- 47 + 8951 = 8998
- 131 + 8867 = 8998
- 137 + 8861 = 8998
- 149 + 8849 = 8998
- 167 + 8831 = 8998
- 179 + 8819 = 8998
- 191 + 8807 = 8998
Showing the first eight; more decompositions exist.
