Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8862, here are decompositions:
- 13 + 8849 = 8862
- 23 + 8839 = 8862
- 31 + 8831 = 8862
- 41 + 8821 = 8862
- 43 + 8819 = 8862
- 59 + 8803 = 8862
- 79 + 8783 = 8862
- 83 + 8779 = 8862
Showing the first eight; more decompositions exist.
