Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536224, here are decompositions:
- 37 + 31536187 = 31536224
- 127 + 31536097 = 31536224
- 163 + 31536061 = 31536224
- 241 + 31535983 = 31536224
- 277 + 31535947 = 31536224
- 283 + 31535941 = 31536224
- 397 + 31535827 = 31536224
- 631 + 31535593 = 31536224
Showing the first eight; more decompositions exist.
