Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71998, here are decompositions:
- 5 + 71993 = 71998
- 11 + 71987 = 71998
- 89 + 71909 = 71998
- 131 + 71867 = 71998
- 137 + 71861 = 71998
- 149 + 71849 = 71998
- 191 + 71807 = 71998
- 257 + 71741 = 71998
Showing the first eight; more decompositions exist.
