Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61998, here are decompositions:
- 7 + 61991 = 61998
- 11 + 61987 = 61998
- 17 + 61981 = 61998
- 19 + 61979 = 61998
- 31 + 61967 = 61998
- 37 + 61961 = 61998
- 71 + 61927 = 61998
- 89 + 61909 = 61998
Showing the first eight; more decompositions exist.
