Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78998, here are decompositions:
- 19 + 78979 = 78998
- 79 + 78919 = 78998
- 97 + 78901 = 78998
- 109 + 78889 = 78998
- 211 + 78787 = 78998
- 277 + 78721 = 78998
- 307 + 78691 = 78998
- 349 + 78649 = 78998
Showing the first eight; more decompositions exist.
