Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8182, here are decompositions:
- 3 + 8179 = 8182
- 11 + 8171 = 8182
- 59 + 8123 = 8182
- 71 + 8111 = 8182
- 89 + 8093 = 8182
- 101 + 8081 = 8182
- 113 + 8069 = 8182
- 173 + 8009 = 8182
Showing the first eight; more decompositions exist.
