Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8864, here are decompositions:
- 3 + 8861 = 8864
- 43 + 8821 = 8864
- 61 + 8803 = 8864
- 103 + 8761 = 8864
- 127 + 8737 = 8864
- 151 + 8713 = 8864
- 157 + 8707 = 8864
- 223 + 8641 = 8864
Showing the first eight; more decompositions exist.
