Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26988, here are decompositions:
- 7 + 26981 = 26988
- 29 + 26959 = 26988
- 37 + 26951 = 26988
- 41 + 26947 = 26988
- 61 + 26927 = 26988
- 67 + 26921 = 26988
- 97 + 26891 = 26988
- 107 + 26881 = 26988
Showing the first eight; more decompositions exist.
