Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8860, here are decompositions:
- 11 + 8849 = 8860
- 23 + 8837 = 8860
- 29 + 8831 = 8860
- 41 + 8819 = 8860
- 53 + 8807 = 8860
- 107 + 8753 = 8860
- 113 + 8747 = 8860
- 167 + 8693 = 8860
Showing the first eight; more decompositions exist.
