Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78888, here are decompositions:
- 11 + 78877 = 78888
- 31 + 78857 = 78888
- 79 + 78809 = 78888
- 97 + 78791 = 78888
- 101 + 78787 = 78888
- 107 + 78781 = 78888
- 109 + 78779 = 78888
- 151 + 78737 = 78888
Showing the first eight; more decompositions exist.
