Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26980, here are decompositions:
- 29 + 26951 = 26980
- 53 + 26927 = 26980
- 59 + 26921 = 26980
- 89 + 26891 = 26980
- 101 + 26879 = 26980
- 131 + 26849 = 26980
- 167 + 26813 = 26980
- 179 + 26801 = 26980
Showing the first eight; more decompositions exist.
