Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78750, here are decompositions:
- 13 + 78737 = 78750
- 29 + 78721 = 78750
- 37 + 78713 = 78750
- 43 + 78707 = 78750
- 53 + 78697 = 78750
- 59 + 78691 = 78750
- 97 + 78653 = 78750
- 101 + 78649 = 78750
Showing the first eight; more decompositions exist.
