Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720718, here are decompositions:
- 5 + 8720713 = 8720718
- 11 + 8720707 = 8720718
- 29 + 8720689 = 8720718
- 31 + 8720687 = 8720718
- 37 + 8720681 = 8720718
- 47 + 8720671 = 8720718
- 89 + 8720629 = 8720718
- 101 + 8720617 = 8720718
Showing the first eight; more decompositions exist.
