Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722122, here are decompositions:
- 5 + 8722117 = 8722122
- 23 + 8722099 = 8722122
- 29 + 8722093 = 8722122
- 41 + 8722081 = 8722122
- 43 + 8722079 = 8722122
- 89 + 8722033 = 8722122
- 103 + 8722019 = 8722122
- 113 + 8722009 = 8722122
Showing the first eight; more decompositions exist.
