Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43872, here are decompositions:
- 5 + 43867 = 43872
- 19 + 43853 = 43872
- 71 + 43801 = 43872
- 79 + 43793 = 43872
- 83 + 43789 = 43872
- 89 + 43783 = 43872
- 113 + 43759 = 43872
- 151 + 43721 = 43872
Showing the first eight; more decompositions exist.
