Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2718, here are decompositions:
- 5 + 2713 = 2718
- 7 + 2711 = 2718
- 11 + 2707 = 2718
- 19 + 2699 = 2718
- 29 + 2689 = 2718
- 31 + 2687 = 2718
- 41 + 2677 = 2718
- 47 + 2671 = 2718
Showing the first eight; more decompositions exist.
