Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82140, here are decompositions:
- 11 + 82129 = 82140
- 67 + 82073 = 82140
- 73 + 82067 = 82140
- 89 + 82051 = 82140
- 101 + 82039 = 82140
- 103 + 82037 = 82140
- 109 + 82031 = 82140
- 127 + 82013 = 82140
Showing the first eight; more decompositions exist.
