Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91224, here are decompositions:
- 31 + 91193 = 91224
- 41 + 91183 = 91224
- 61 + 91163 = 91224
- 71 + 91153 = 91224
- 73 + 91151 = 91224
- 83 + 91141 = 91224
- 97 + 91127 = 91224
- 103 + 91121 = 91224
Showing the first eight; more decompositions exist.
