Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8228, here are decompositions:
- 7 + 8221 = 8228
- 19 + 8209 = 8228
- 37 + 8191 = 8228
- 61 + 8167 = 8228
- 67 + 8161 = 8228
- 127 + 8101 = 8228
- 139 + 8089 = 8228
- 211 + 8017 = 8228
Showing the first eight; more decompositions exist.
