Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30146, here are decompositions:
- 7 + 30139 = 30146
- 13 + 30133 = 30146
- 37 + 30109 = 30146
- 43 + 30103 = 30146
- 157 + 29989 = 30146
- 163 + 29983 = 30146
- 199 + 29947 = 30146
- 229 + 29917 = 30146
Showing the first eight; more decompositions exist.
