Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43772, here are decompositions:
- 13 + 43759 = 43772
- 19 + 43753 = 43772
- 61 + 43711 = 43772
- 103 + 43669 = 43772
- 139 + 43633 = 43772
- 163 + 43609 = 43772
- 181 + 43591 = 43772
- 193 + 43579 = 43772
Showing the first eight; more decompositions exist.
