Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43790, here are decompositions:
- 3 + 43787 = 43790
- 7 + 43783 = 43790
- 13 + 43777 = 43790
- 31 + 43759 = 43790
- 37 + 43753 = 43790
- 73 + 43717 = 43790
- 79 + 43711 = 43790
- 139 + 43651 = 43790
Showing the first eight; more decompositions exist.
