Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78860, here are decompositions:
- 3 + 78857 = 78860
- 7 + 78853 = 78860
- 37 + 78823 = 78860
- 73 + 78787 = 78860
- 79 + 78781 = 78860
- 139 + 78721 = 78860
- 163 + 78697 = 78860
- 211 + 78649 = 78860
Showing the first eight; more decompositions exist.
