Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8842, here are decompositions:
- 3 + 8839 = 8842
- 5 + 8837 = 8842
- 11 + 8831 = 8842
- 23 + 8819 = 8842
- 59 + 8783 = 8842
- 89 + 8753 = 8842
- 101 + 8741 = 8842
- 149 + 8693 = 8842
Showing the first eight; more decompositions exist.
