Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42198, here are decompositions:
- 5 + 42193 = 42198
- 11 + 42187 = 42198
- 17 + 42181 = 42198
- 19 + 42179 = 42198
- 29 + 42169 = 42198
- 41 + 42157 = 42198
- 59 + 42139 = 42198
- 67 + 42131 = 42198
Showing the first eight; more decompositions exist.
