Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43820, here are decompositions:
- 19 + 43801 = 43820
- 31 + 43789 = 43820
- 37 + 43783 = 43820
- 43 + 43777 = 43820
- 61 + 43759 = 43820
- 67 + 43753 = 43820
- 103 + 43717 = 43820
- 109 + 43711 = 43820
Showing the first eight; more decompositions exist.
