Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8226, here are decompositions:
- 5 + 8221 = 8226
- 7 + 8219 = 8226
- 17 + 8209 = 8226
- 47 + 8179 = 8226
- 59 + 8167 = 8226
- 79 + 8147 = 8226
- 103 + 8123 = 8226
- 109 + 8117 = 8226
Showing the first eight; more decompositions exist.
