Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527224, here are decompositions:
- 13 + 31527211 = 31527224
- 31 + 31527193 = 31527224
- 67 + 31527157 = 31527224
- 73 + 31527151 = 31527224
- 271 + 31526953 = 31527224
- 283 + 31526941 = 31527224
- 331 + 31526893 = 31527224
- 433 + 31526791 = 31527224
Showing the first eight; more decompositions exist.
