Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8900, here are decompositions:
- 7 + 8893 = 8900
- 13 + 8887 = 8900
- 37 + 8863 = 8900
- 61 + 8839 = 8900
- 79 + 8821 = 8900
- 97 + 8803 = 8900
- 139 + 8761 = 8900
- 163 + 8737 = 8900
Showing the first eight; more decompositions exist.
