Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43838, here are decompositions:
- 37 + 43801 = 43838
- 61 + 43777 = 43838
- 79 + 43759 = 43838
- 127 + 43711 = 43838
- 211 + 43627 = 43838
- 229 + 43609 = 43838
- 241 + 43597 = 43838
- 397 + 43441 = 43838
Showing the first eight; more decompositions exist.
