Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78788, here are decompositions:
- 7 + 78781 = 78788
- 67 + 78721 = 78788
- 97 + 78691 = 78788
- 139 + 78649 = 78788
- 181 + 78607 = 78788
- 211 + 78577 = 78788
- 271 + 78517 = 78788
- 277 + 78511 = 78788
Showing the first eight; more decompositions exist.
