Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80972, here are decompositions:
- 19 + 80953 = 80972
- 43 + 80929 = 80972
- 61 + 80911 = 80972
- 109 + 80863 = 80972
- 139 + 80833 = 80972
- 163 + 80809 = 80972
- 193 + 80779 = 80972
- 211 + 80761 = 80972
Showing the first eight; more decompositions exist.
