Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6986, here are decompositions:
- 3 + 6983 = 6986
- 19 + 6967 = 6986
- 37 + 6949 = 6986
- 79 + 6907 = 6986
- 103 + 6883 = 6986
- 157 + 6829 = 6986
- 163 + 6823 = 6986
- 193 + 6793 = 6986
Showing the first eight; more decompositions exist.
