Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 888, here are decompositions:
- 5 + 883 = 888
- 7 + 881 = 888
- 11 + 877 = 888
- 29 + 859 = 888
- 31 + 857 = 888
- 59 + 829 = 888
- 61 + 827 = 888
- 67 + 821 = 888
Showing the first eight; more decompositions exist.
