Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8122, here are decompositions:
- 5 + 8117 = 8122
- 11 + 8111 = 8122
- 29 + 8093 = 8122
- 41 + 8081 = 8122
- 53 + 8069 = 8122
- 83 + 8039 = 8122
- 113 + 8009 = 8122
- 173 + 7949 = 8122
Showing the first eight; more decompositions exist.
