Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11878, here are decompositions:
- 11 + 11867 = 11878
- 47 + 11831 = 11878
- 71 + 11807 = 11878
- 89 + 11789 = 11878
- 101 + 11777 = 11878
- 179 + 11699 = 11878
- 197 + 11681 = 11878
- 257 + 11621 = 11878
Showing the first eight; more decompositions exist.
