Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82078, here are decompositions:
- 5 + 82073 = 82078
- 11 + 82067 = 82078
- 41 + 82037 = 82078
- 47 + 82031 = 82078
- 71 + 82007 = 82078
- 107 + 81971 = 82078
- 149 + 81929 = 82078
- 179 + 81899 = 82078
Showing the first eight; more decompositions exist.
