Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43764, here are decompositions:
- 5 + 43759 = 43764
- 11 + 43753 = 43764
- 43 + 43721 = 43764
- 47 + 43717 = 43764
- 53 + 43711 = 43764
- 73 + 43691 = 43764
- 103 + 43661 = 43764
- 113 + 43651 = 43764
Showing the first eight; more decompositions exist.
