Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722008, here are decompositions:
- 7 + 8722001 = 8722008
- 11 + 8721997 = 8722008
- 19 + 8721989 = 8722008
- 67 + 8721941 = 8722008
- 79 + 8721929 = 8722008
- 101 + 8721907 = 8722008
- 131 + 8721877 = 8722008
- 157 + 8721851 = 8722008
Showing the first eight; more decompositions exist.
