Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20030, here are decompositions:
- 7 + 20023 = 20030
- 19 + 20011 = 20030
- 37 + 19993 = 20030
- 67 + 19963 = 20030
- 103 + 19927 = 20030
- 139 + 19891 = 20030
- 163 + 19867 = 20030
- 211 + 19819 = 20030
Showing the first eight; more decompositions exist.
