Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4098, here are decompositions:
- 5 + 4093 = 4098
- 7 + 4091 = 4098
- 19 + 4079 = 4098
- 41 + 4057 = 4098
- 47 + 4051 = 4098
- 71 + 4027 = 4098
- 79 + 4019 = 4098
- 97 + 4001 = 4098
Showing the first eight; more decompositions exist.
