Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78000, here are decompositions:
- 17 + 77983 = 78000
- 23 + 77977 = 78000
- 31 + 77969 = 78000
- 67 + 77933 = 78000
- 71 + 77929 = 78000
- 101 + 77899 = 78000
- 107 + 77893 = 78000
- 137 + 77863 = 78000
Showing the first eight; more decompositions exist.
