Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10218, here are decompositions:
- 7 + 10211 = 10218
- 37 + 10181 = 10218
- 41 + 10177 = 10218
- 59 + 10159 = 10218
- 67 + 10151 = 10218
- 79 + 10139 = 10218
- 107 + 10111 = 10218
- 127 + 10091 = 10218
Showing the first eight; more decompositions exist.
