Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80966, here are decompositions:
- 3 + 80963 = 80966
- 13 + 80953 = 80966
- 37 + 80929 = 80966
- 43 + 80923 = 80966
- 103 + 80863 = 80966
- 157 + 80809 = 80966
- 163 + 80803 = 80966
- 229 + 80737 = 80966
Showing the first eight; more decompositions exist.
