Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80194, here are decompositions:
- 3 + 80191 = 80194
- 17 + 80177 = 80194
- 41 + 80153 = 80194
- 47 + 80147 = 80194
- 53 + 80141 = 80194
- 83 + 80111 = 80194
- 173 + 80021 = 80194
- 197 + 79997 = 80194
Showing the first eight; more decompositions exist.
