Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43770, here are decompositions:
- 11 + 43759 = 43770
- 17 + 43753 = 43770
- 53 + 43717 = 43770
- 59 + 43711 = 43770
- 79 + 43691 = 43770
- 101 + 43669 = 43770
- 109 + 43661 = 43770
- 137 + 43633 = 43770
Showing the first eight; more decompositions exist.
