Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671992, here are decompositions:
- 5 + 8671987 = 8671992
- 11 + 8671981 = 8671992
- 13 + 8671979 = 8671992
- 73 + 8671919 = 8671992
- 181 + 8671811 = 8671992
- 223 + 8671769 = 8671992
- 271 + 8671721 = 8671992
- 281 + 8671711 = 8671992
Showing the first eight; more decompositions exist.
