Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30830, here are decompositions:
- 13 + 30817 = 30830
- 67 + 30763 = 30830
- 73 + 30757 = 30830
- 103 + 30727 = 30830
- 127 + 30703 = 30830
- 181 + 30649 = 30830
- 193 + 30637 = 30830
- 199 + 30631 = 30830
Showing the first eight; more decompositions exist.
