Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78198, here are decompositions:
- 5 + 78193 = 78198
- 7 + 78191 = 78198
- 19 + 78179 = 78198
- 31 + 78167 = 78198
- 41 + 78157 = 78198
- 59 + 78139 = 78198
- 61 + 78137 = 78198
- 97 + 78101 = 78198
Showing the first eight; more decompositions exist.
