Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 958, here are decompositions:
- 5 + 953 = 958
- 11 + 947 = 958
- 17 + 941 = 958
- 29 + 929 = 958
- 47 + 911 = 958
- 71 + 887 = 958
- 101 + 857 = 958
- 131 + 827 = 958
Showing the first eight; more decompositions exist.
