Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8888, here are decompositions:
- 67 + 8821 = 8888
- 109 + 8779 = 8888
- 127 + 8761 = 8888
- 151 + 8737 = 8888
- 157 + 8731 = 8888
- 181 + 8707 = 8888
- 199 + 8689 = 8888
- 211 + 8677 = 8888
Showing the first eight; more decompositions exist.
