Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78446, here are decompositions:
- 7 + 78439 = 78446
- 19 + 78427 = 78446
- 79 + 78367 = 78446
- 139 + 78307 = 78446
- 163 + 78283 = 78446
- 283 + 78163 = 78446
- 307 + 78139 = 78446
- 367 + 78079 = 78446
Showing the first eight; more decompositions exist.
