Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43812, here are decompositions:
- 11 + 43801 = 43812
- 19 + 43793 = 43812
- 23 + 43789 = 43812
- 29 + 43783 = 43812
- 31 + 43781 = 43812
- 53 + 43759 = 43812
- 59 + 43753 = 43812
- 101 + 43711 = 43812
Showing the first eight; more decompositions exist.
