Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77700, here are decompositions:
- 11 + 77689 = 77700
- 13 + 77687 = 77700
- 19 + 77681 = 77700
- 41 + 77659 = 77700
- 53 + 77647 = 77700
- 59 + 77641 = 77700
- 79 + 77621 = 77700
- 83 + 77617 = 77700
Showing the first eight; more decompositions exist.
