Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80188, here are decompositions:
- 11 + 80177 = 80188
- 41 + 80147 = 80188
- 47 + 80141 = 80188
- 137 + 80051 = 80188
- 149 + 80039 = 80188
- 167 + 80021 = 80188
- 191 + 79997 = 80188
- 281 + 79907 = 80188
Showing the first eight; more decompositions exist.
