Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527328, here are decompositions:
- 5 + 31527323 = 31527328
- 11 + 31527317 = 31527328
- 17 + 31527311 = 31527328
- 137 + 31527191 = 31527328
- 179 + 31527149 = 31527328
- 197 + 31527131 = 31527328
- 251 + 31527077 = 31527328
- 281 + 31527047 = 31527328
Showing the first eight; more decompositions exist.
