Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671824, here are decompositions:
- 13 + 8671811 = 8671824
- 103 + 8671721 = 8671824
- 113 + 8671711 = 8671824
- 127 + 8671697 = 8671824
- 191 + 8671633 = 8671824
- 193 + 8671631 = 8671824
- 241 + 8671583 = 8671824
- 251 + 8671573 = 8671824
Showing the first eight; more decompositions exist.
