Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30218, here are decompositions:
- 7 + 30211 = 30218
- 31 + 30187 = 30218
- 37 + 30181 = 30218
- 79 + 30139 = 30218
- 109 + 30109 = 30218
- 127 + 30091 = 30218
- 229 + 29989 = 30218
- 271 + 29947 = 30218
Showing the first eight; more decompositions exist.
