Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30170, here are decompositions:
- 31 + 30139 = 30170
- 37 + 30133 = 30170
- 61 + 30109 = 30170
- 67 + 30103 = 30170
- 73 + 30097 = 30170
- 79 + 30091 = 30170
- 157 + 30013 = 30170
- 181 + 29989 = 30170
Showing the first eight; more decompositions exist.
