Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77718, here are decompositions:
- 5 + 77713 = 77718
- 7 + 77711 = 77718
- 19 + 77699 = 77718
- 29 + 77689 = 77718
- 31 + 77687 = 77718
- 37 + 77681 = 77718
- 59 + 77659 = 77718
- 71 + 77647 = 77718
Showing the first eight; more decompositions exist.
