Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77688, here are decompositions:
- 7 + 77681 = 77688
- 29 + 77659 = 77688
- 41 + 77647 = 77688
- 47 + 77641 = 77688
- 67 + 77621 = 77688
- 71 + 77617 = 77688
- 97 + 77591 = 77688
- 101 + 77587 = 77688
Showing the first eight; more decompositions exist.
