Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149224, here are decompositions:
- 11 + 149213 = 149224
- 41 + 149183 = 149224
- 71 + 149153 = 149224
- 113 + 149111 = 149224
- 137 + 149087 = 149224
- 167 + 149057 = 149224
- 191 + 149033 = 149224
- 197 + 149027 = 149224
Showing the first eight; more decompositions exist.
