Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543224, here are decompositions:
- 5 + 31543219 = 31543224
- 7 + 31543217 = 31543224
- 17 + 31543207 = 31543224
- 43 + 31543181 = 31543224
- 61 + 31543163 = 31543224
- 157 + 31543067 = 31543224
- 233 + 31542991 = 31543224
- 257 + 31542967 = 31543224
Showing the first eight; more decompositions exist.
