Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535224, here are decompositions:
- 5 + 31535219 = 31535224
- 11 + 31535213 = 31535224
- 41 + 31535183 = 31535224
- 53 + 31535171 = 31535224
- 101 + 31535123 = 31535224
- 167 + 31535057 = 31535224
- 191 + 31535033 = 31535224
- 263 + 31534961 = 31535224
Showing the first eight; more decompositions exist.
