Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80158, here are decompositions:
- 5 + 80153 = 80158
- 11 + 80147 = 80158
- 17 + 80141 = 80158
- 47 + 80111 = 80158
- 107 + 80051 = 80158
- 137 + 80021 = 80158
- 179 + 79979 = 80158
- 191 + 79967 = 80158
Showing the first eight; more decompositions exist.
