Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22224, here are decompositions:
- 31 + 22193 = 22224
- 53 + 22171 = 22224
- 67 + 22157 = 22224
- 71 + 22153 = 22224
- 101 + 22123 = 22224
- 113 + 22111 = 22224
- 131 + 22093 = 22224
- 151 + 22073 = 22224
Showing the first eight; more decompositions exist.
