Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30040, here are decompositions:
- 11 + 30029 = 30040
- 29 + 30011 = 30040
- 113 + 29927 = 30040
- 167 + 29873 = 30040
- 173 + 29867 = 30040
- 251 + 29789 = 30040
- 281 + 29759 = 30040
- 317 + 29723 = 30040
Showing the first eight; more decompositions exist.
