Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8958, here are decompositions:
- 7 + 8951 = 8958
- 17 + 8941 = 8958
- 29 + 8929 = 8958
- 71 + 8887 = 8958
- 97 + 8861 = 8958
- 109 + 8849 = 8958
- 127 + 8831 = 8958
- 137 + 8821 = 8958
Showing the first eight; more decompositions exist.
