Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10220, here are decompositions:
- 43 + 10177 = 10220
- 61 + 10159 = 10220
- 79 + 10141 = 10220
- 109 + 10111 = 10220
- 127 + 10093 = 10220
- 151 + 10069 = 10220
- 181 + 10039 = 10220
- 211 + 10009 = 10220
Showing the first eight; more decompositions exist.
