Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43988, here are decompositions:
- 19 + 43969 = 43988
- 37 + 43951 = 43988
- 97 + 43891 = 43988
- 199 + 43789 = 43988
- 211 + 43777 = 43988
- 229 + 43759 = 43988
- 271 + 43717 = 43988
- 277 + 43711 = 43988
Showing the first eight; more decompositions exist.
