Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30042, here are decompositions:
- 13 + 30029 = 30042
- 29 + 30013 = 30042
- 31 + 30011 = 30042
- 53 + 29989 = 30042
- 59 + 29983 = 30042
- 83 + 29959 = 30042
- 163 + 29879 = 30042
- 179 + 29863 = 30042
Showing the first eight; more decompositions exist.
