Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80178, here are decompositions:
- 5 + 80173 = 80178
- 11 + 80167 = 80178
- 29 + 80149 = 80178
- 31 + 80147 = 80178
- 37 + 80141 = 80178
- 67 + 80111 = 80178
- 71 + 80107 = 80178
- 101 + 80077 = 80178
Showing the first eight; more decompositions exist.
