Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80942, here are decompositions:
- 13 + 80929 = 80942
- 19 + 80923 = 80942
- 31 + 80911 = 80942
- 79 + 80863 = 80942
- 109 + 80833 = 80942
- 139 + 80803 = 80942
- 163 + 80779 = 80942
- 181 + 80761 = 80942
Showing the first eight; more decompositions exist.
