Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006, here are decompositions:
- 23 + 983 = 1006
- 29 + 977 = 1006
- 53 + 953 = 1006
- 59 + 947 = 1006
- 149 + 857 = 1006
- 167 + 839 = 1006
- 179 + 827 = 1006
- 197 + 809 = 1006
Showing the first eight; more decompositions exist.
