Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722224, here are decompositions:
- 13 + 8722211 = 8722224
- 31 + 8722193 = 8722224
- 37 + 8722187 = 8722224
- 53 + 8722171 = 8722224
- 101 + 8722123 = 8722224
- 107 + 8722117 = 8722224
- 127 + 8722097 = 8722224
- 131 + 8722093 = 8722224
Showing the first eight; more decompositions exist.
