Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78920, here are decompositions:
- 19 + 78901 = 78920
- 31 + 78889 = 78920
- 43 + 78877 = 78920
- 67 + 78853 = 78920
- 97 + 78823 = 78920
- 139 + 78781 = 78920
- 199 + 78721 = 78920
- 223 + 78697 = 78920
Showing the first eight; more decompositions exist.
