Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43842, here are decompositions:
- 41 + 43801 = 43842
- 53 + 43789 = 43842
- 59 + 43783 = 43842
- 61 + 43781 = 43842
- 83 + 43759 = 43842
- 89 + 43753 = 43842
- 131 + 43711 = 43842
- 151 + 43691 = 43842
Showing the first eight; more decompositions exist.
