Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82990, here are decompositions:
- 101 + 82889 = 82990
- 107 + 82883 = 82990
- 179 + 82811 = 82990
- 191 + 82799 = 82990
- 197 + 82793 = 82990
- 227 + 82763 = 82990
- 233 + 82757 = 82990
- 263 + 82727 = 82990
Showing the first eight; more decompositions exist.
