Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30026, here are decompositions:
- 13 + 30013 = 30026
- 37 + 29989 = 30026
- 43 + 29983 = 30026
- 67 + 29959 = 30026
- 79 + 29947 = 30026
- 109 + 29917 = 30026
- 163 + 29863 = 30026
- 193 + 29833 = 30026
Showing the first eight; more decompositions exist.
