Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86980, here are decompositions:
- 11 + 86969 = 86980
- 29 + 86951 = 86980
- 41 + 86939 = 86980
- 53 + 86927 = 86980
- 137 + 86843 = 86980
- 167 + 86813 = 86980
- 197 + 86783 = 86980
- 227 + 86753 = 86980
Showing the first eight; more decompositions exist.
