Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8856, here are decompositions:
- 7 + 8849 = 8856
- 17 + 8839 = 8856
- 19 + 8837 = 8856
- 37 + 8819 = 8856
- 53 + 8803 = 8856
- 73 + 8783 = 8856
- 103 + 8753 = 8856
- 109 + 8747 = 8856
Showing the first eight; more decompositions exist.
