Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64224, here are decompositions:
- 7 + 64217 = 64224
- 37 + 64187 = 64224
- 53 + 64171 = 64224
- 67 + 64157 = 64224
- 71 + 64153 = 64224
- 73 + 64151 = 64224
- 101 + 64123 = 64224
- 157 + 64067 = 64224
Showing the first eight; more decompositions exist.
