Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56220, here are decompositions:
- 11 + 56209 = 56220
- 13 + 56207 = 56220
- 23 + 56197 = 56220
- 41 + 56179 = 56220
- 53 + 56167 = 56220
- 71 + 56149 = 56220
- 89 + 56131 = 56220
- 97 + 56123 = 56220
Showing the first eight; more decompositions exist.
