Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492224, here are decompositions:
- 11 + 31492213 = 31492224
- 61 + 31492163 = 31492224
- 67 + 31492157 = 31492224
- 131 + 31492093 = 31492224
- 151 + 31492073 = 31492224
- 157 + 31492067 = 31492224
- 163 + 31492061 = 31492224
- 173 + 31492051 = 31492224
Showing the first eight; more decompositions exist.
