Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89908, here are decompositions:
- 11 + 89897 = 89908
- 17 + 89891 = 89908
- 41 + 89867 = 89908
- 59 + 89849 = 89908
- 89 + 89819 = 89908
- 149 + 89759 = 89908
- 227 + 89681 = 89908
- 239 + 89669 = 89908
Showing the first eight; more decompositions exist.
