Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722164, here are decompositions:
- 41 + 8722123 = 8722164
- 47 + 8722117 = 8722164
- 67 + 8722097 = 8722164
- 71 + 8722093 = 8722164
- 83 + 8722081 = 8722164
- 131 + 8722033 = 8722164
- 137 + 8722027 = 8722164
- 163 + 8722001 = 8722164
Showing the first eight; more decompositions exist.
