Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637984, here are decompositions:
- 11 + 8637973 = 8637984
- 31 + 8637953 = 8637984
- 41 + 8637943 = 8637984
- 137 + 8637847 = 8637984
- 163 + 8637821 = 8637984
- 193 + 8637791 = 8637984
- 197 + 8637787 = 8637984
- 283 + 8637701 = 8637984
Showing the first eight; more decompositions exist.
