Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80170, here are decompositions:
- 3 + 80167 = 80170
- 17 + 80153 = 80170
- 23 + 80147 = 80170
- 29 + 80141 = 80170
- 59 + 80111 = 80170
- 131 + 80039 = 80170
- 149 + 80021 = 80170
- 173 + 79997 = 80170
Showing the first eight; more decompositions exist.
