Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78942, here are decompositions:
- 13 + 78929 = 78942
- 23 + 78919 = 78942
- 41 + 78901 = 78942
- 53 + 78889 = 78942
- 89 + 78853 = 78942
- 103 + 78839 = 78942
- 139 + 78803 = 78942
- 151 + 78791 = 78942
Showing the first eight; more decompositions exist.
