Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18030, here are decompositions:
- 17 + 18013 = 18030
- 41 + 17989 = 18030
- 43 + 17987 = 18030
- 53 + 17977 = 18030
- 59 + 17971 = 18030
- 71 + 17959 = 18030
- 73 + 17957 = 18030
- 101 + 17929 = 18030
Showing the first eight; more decompositions exist.
