Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30086, here are decompositions:
- 73 + 30013 = 30086
- 97 + 29989 = 30086
- 103 + 29983 = 30086
- 127 + 29959 = 30086
- 139 + 29947 = 30086
- 223 + 29863 = 30086
- 283 + 29803 = 30086
- 457 + 29629 = 30086
Showing the first eight; more decompositions exist.
