Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82878, here are decompositions:
- 31 + 82847 = 82878
- 41 + 82837 = 82878
- 67 + 82811 = 82878
- 79 + 82799 = 82878
- 97 + 82781 = 82878
- 149 + 82729 = 82878
- 151 + 82727 = 82878
- 157 + 82721 = 82878
Showing the first eight; more decompositions exist.
